    Bluetooth

    Bluetooth is a new technology that utilises radio frequency waves as a way to communicate wirelessly between digital devices. It sets up personal area networks that incorporate all of a persons digital devices into one system for both convergence and convenience.

    Wireless- History

    Many people put the invention of [wireless] radio down to Guglielmo Marconi, who in 1895 sent the first radio telegraph transmission across the English Channel. Only twelve years later radio began being used in the public sphere. [Mathias, p.2] Up until then however, many wireless pioneers conducted trials across lakes where the antenna used to transmit the signal was longer than the distance across the lake. [Brodsky, p. 3] After its introduction the main use of wireless radio was for military communications where its first use was for the Boer War. [Flichy, p. 103] The invention of broadcast radio ensured the feasibility of wireless technologies. [Morrow, p. 2] By the 1920s, radio had become a well-recognised mass medium. [Flichy, p. 111] From the 1980s until now, wireless communications have been through several stages, from 1G (analogue signal), 2G (digital signal) and 3G (always on, faster data rate). [Lightman and Rojas, p. 3] The history of Bluetooth is a much more recent one, with the first Bluetooth-enabled products coming into existence in 2000. Named after Harald Blatand the first, king of Denmark around twelve hundred years ago, who joined the Danish and Norwegian kingdoms, Bluetooth technology is founded on this same unifying principle of being able to unite the computer and telecommunication industr[ies]. [Ganguli, p. 5] In 1994 the Ericsson Company began looking into the idea of replacing cables connecting accessories to mobile phones and computers with wireless links, and this became the main inspiration behind Bluetooth. [Morrow, p. 10]

    Wireless- Technologies

    Bluetooth is not the only wireless technology currently being developed and utilised. Other wireless technologies, including 802.11b, otherwise known as Wi-Fi, Infrared Data Association (IrDA), Ultra- Wideband Radio (UWB), and Home RF are being applied to similar technologies that Bluetooth use with mixed results. 802.11 is the most well known technology, excluding Bluetooth, and uses the same radio frequency, meaning that they are not compatible as they cause interference with each other. 802.11 is being implemented into universities in the US, Japan and China, as well as food and beverage shops where they are being used to identify students and customers. Even airports have taken up the 802.11 technology, with airports all over America, and three of Americas most prominent airlines promoting the use of it. [Lightman and Rojas, p. 202-3] Infrared Data Association is extremely inferior to that of Bluetooth. Its limitations include only being able to communicate point-to-point, needing a line of sight, and it has a speed of fifty- six kilobytes per second, whereas Bluetooth is one megabyte per second. [Ganguli, p. 17] The Ultra- Wideband Radio is superior to that of Bluetooth in that it can transmit at greater lengths (up to 70 metres), with only half of the power that Bluetooth uses. [Ganguli, p.17] HomeRF is a technology that is not very well known. It is used for data and voice communication and targeted for the residential market segment and does not serve enterprise- class WLANs, public access systems or fixed wireless Internet access. [Ganguli, p.17-18]

    Bluetooth- Technical Introduction

    Bluetooth is a short- range radio device that replaces cables with low power radio waves to connect electronic devices, whether they are portable or fixed. The Bluetooth device also uses frequency hopping to ensure a secure, quality link, and it uses ad hoc networks, meaning that it connects peer-to-peer. It can be operated worldwide and without a network because it uses the unlicensed Industrial- Scientific Medical (ISM) band for transmission that varies with a change in location. [Ganguli, p. 25-6] The Bluetooth user has the choice of point-to-point or point-to-multipoint links whereby communication can be held between two devices, or up to eight. [Ganguli, p. 96] When devices are communicating with each other they are known as piconets, and each device is designated as a master unit or slave unit, usually depending on who initiates the connection. However, both devices have the potential to be either a master or a slave. [Swaminatha and Elden, p. 49]

    Bluetooth- Advantages

    There are many advantages to using Bluetooth wireless technologies including the use of a radio frequency, the inexpensive cost of the device, replacing tedious cable connections, the low power use and implemented security measures. The use of an unlicensed radio frequency ensures that users do not need to gain a license in order to use it. Unlike Infrared which needs to have a line of sight in order to work, Bluetooth radio waves are omnidirectional and do not need a clear path. The device itself is relatively cheap and easy to use, one can be bought for around ten American dollars, and this price is currently decreasing. Compare this to the expensive cost of implementing hundreds of cables and wires into an office and there is no competition. Of course, this is the main reason for the take -up in Bluetooth -enabled devices; it does away with cables. Another of Bluetooths advantages is its low power use, ensuring that battery operated devices such as mobile phones and personal digital assistants wont have their battery life drained with the use of it. This low power consumption also guarantees minimal interruption from other radio operated and wireless devices that operate at a higher power. Bluetooth has several enabled security measures that ensures a level of privacy and security, including frequency hopping, whereby the device changes radio frequency sixteen hundred times per second. Also within the security tools are encryption and authentification mechanisms that guarantee little interference by unauthorised hackers. [Ganguli, p. 330] One of the best advantages of Bluetooth devices, especially the hands free device that connects to a mobile phone, is that it removes radiation from the brain region. [Tsang, p.1]

    Bluetooth- Applications

    The applications that are in development or current use for the Bluetooth technology include such areas as automotive, medical, industrial equipment, output equipment, digital -still cameras, computers, and communications systems. [Lightman and Rojas, p. 201] Bluetooth is an ad hoc network user, and therefore it may be used for social networking, i.e. people can meet and share files or link their Bluetooth devices together to play games or other such activities. [Smyth, p. 70] Using Bluetooth, a mobile phone can become a three- way phone, where at home it connects to a landline for cheaper calls, on the move it acts as a mobile phone and when it comes in contact with another Bluetooth-enabled phone it acts as a walkie- talkie. This walkie- talkie option allows for free interaction and communication, as Bluetooth is not connected to any telecommunications network. [Gupta, p.1] Bluetooth also allows automatic synchronization of your desktop, mobile computer, notebook and your mobile phone for the user to have all of their data managed as one. [Gupta, p.1]

    Bluetooth- Security Issues

    Bluetooth has several threats which range in level of risk and how widespread the action is. These threats have the ability to provide criminals with sensitive information on both corporate and personal levels. The only way to avoid such threats is for manufacturers, distributors, and consumers to be provided with more information on how they are committed, current attack activity and how to combat them. This information can be used on a technical level for manufacturers, it can be used by distributors at retail levels to teach consumers the risks and it can be used directly by consumers to be aware of the threats. The outcome of such research will allow end users of Bluetooth products to have an upper hand in this wireless warfare. Bluetooth security is in early stages with regards to both the attackers, their techniques and consumers understanding of these attacks. Some research has been conducted into what the attackers are doing and how they do it. Adam Laurie of A.L Digital Ltd http://www.thebunker.net/release-bluestumbler.htm is leading the research race in Bluetooth security and is often linked to academic resources. Laurie’s research has uncovered the following capabilities of Bluetooth attacks:

    • Confidential data such as the entire phone book, calender and the phone’s IMEI.
    • Complete memory contents of some mobile phones can be accessed by a previously trusted (“paired”) device that has since been removed from the trusted list.
    • Access can be gained to the AT command set of the device, giving full access to the higher level commands and channels, such as data, voice and messaging.

    Attacks on Bluetooth devices at this stage are relatively new to consumers, and therefore are not widely seen as a real threat. Attacks such as the Bluejack attack are probably more recognised by consumers due to its perceived humorous and novelty nature as well as the ease to Bluejack someone. Users who allow their phone to be Bluejacked open the door to more serious attacks, such as the Backdoor attack which have a low level of awareness amongst consumers as attackers can attach to the device with out the users knowledge. Corporations are starting to understand the risks Bluetooth devices pose, Michael Ciarochi (in Brewin 2004) stated that ‘Bluetooth radios were included in laptop PCs that were being configured by an IT Engineer. It raises the possibility of opening a wireless back door into data stored on the PCs. Such a security weakness would be extremely attractive to hackers. Although Bluetooth invites hackers to such attacks; Bluetooth Venders are playing down the risks, Brewin (2004) said that ‘Bluetooth advocates last week dismissed growing security fears about the short-range wireless technology, saying any flaws are limited to a few mobile-phone models. They also detailed steps that users can take to secure Bluetooth devices’. There are many methods of Bluetooth attacks, the Snarf, the Backdoor, Bluebug, Bluejack and Warnibbling attack are the only recognised attacks at this early stage. Below are explanations of such attacks.

    The SNARF attack

    It is possible for attackers to connect to the device without alerting the user, once in the system sensitive data can be retrieved, such as the phone book, business cards, images, messages and voice messages.

    http://www.salzburgresearch.at/research/gfx/bluesnarf_cebit2004.pdf

    Local Copy: BlueSnarf_CeBIT2004.pdf

    The BACKDOOR attack

    The backdoor attack is a higher concern for Bluetooth users; it allows attackers to establishing a trust relationship through the “pairing” mechanism, but ensuring that the user can not see the target’s register of paired devices. In doing this attackers have access to all the data on the device, as well as access to use the modem or internet; WAP and GPRS gateways may be accessed without the owner’s knowledge or consent.

    The BLUEBUG attack

    This attack gives access to the AT command set, in other words it allows the attacker to make premium priced phone calls, allows the use of SMS, or connection the internet. Attackers can not only use the device for such fraudulent exercises it also allows identity theft to impersonate the user.

    Bluejacking

    Dibble (2004) explained that ‘Just as SMS was spawned, there’s a new craze that’s spreading across parts of Europe. Reportedly, it’s more prominent in the UK, but popular elsewhere too’. Bluejacking allows attackers to send messages to strangers in public via Bluetooth. When the phones ‘pair’ the attacked can write a message to the user. Although it may seem harmless at first, there is a downside. Once connected the attacker may then have access to any data on the users Bluetooth device, which has obvious concerns. Powell (2004: 22) explained that ‘Users can refuse any incoming message or data, so Bluejackers change their username to a short barb or compliment to beat you to the punch. For example, you might receive something along the lines of “Incoming message from: Dude, you’ve been Bluejacked.” Or, “Incoming message from: ROI is overrated.” Bluejacking is regarded as a smaller threat to Bluetooth as users being attacked are aware they have been Bluejacked. This does not mean however that they are aware that sensitive information is being accessed and used in a malicious manner.

    Warnibbling

    Warnibbling is a hacking technique using Redfang, or similar software that allows hackers to reveal corporate or personal sensitive information. Redfang allows hackers to find Bluetooth devices in the area, once found, the software takes you through the process of accessing any data that is stored on that device. Redfang also allows non-discoverable devices to be found. Whitehouse explains when testing Redfang ‘One of the first obstacles we had to overcome was the discovery of non-discoverable devices (it was surprising to see the number of devices that dont by default implement this security measure)’. http://www.atstake.com/research/reports/acrobat/atstake_war_nibbling.pdf

    Future of Bluetooth

    Further information, and somewhat speculation is required for consumers and Bluetooth stakeholders on the future of Bluetooth. Such information will provide a clearer understanding of why security of Bluetooth must be improved. Luo and Lee (2004) provide a short term prediction of where Bluetooth is heading, Europe and Asian countries already offer electronic newspapers, subway tickets, and car parking fees via wireless devices. Collins (2003) says that Bluetooth devices ‘appear to be more secure than 802.11 wireless LANs. However, this situation may not last, as the Bluetooth technology becomes more widespread and attracts greater interest from the hacking community’.

    Bluetooth Wireless Specification

    Source

    This article is about the Bluetooth wireless specification. For King Harold Bluetooth, see Harold I of Denmark

    Bluetooth is an industrial specification for wireless personal area networks (PANs).

    Bluetooth provides a way to connect and exchange information between devices like personal digital assistants (PDAs), mobile phones, laptops, PCs, printers and digital cameras via a secure, low-cost, globally available short range radio frequency.

    Bluetooth lets these devices talk to each other when they come in range, even if they’re not in the same room, as long as they are within 10 metres (32 feet) of each other.

    The spec was first developed by Ericsson, later formalised by the Bluetooth Special Interest Group (SIG). The SIG was formally announced on May 20, 1999. It was established by Sony Ericsson, IBM, Intel, Toshiba and Nokia, and later joined by many other companies as Associate or Adopter members.

    About the name

    The system is named after a Danish king Harald Blåtand (<arold Bluetooth in English), King of Denmark and Norway from 935 and 936 respectively, to 940 known for his unification of previously warring tribes from Denmark, Norway and Sweden. Bluetooth likewise was intended to unify different technologies like computers and mobile phones. The Bluetooth logo merges the Nordic runes for H and B.

    General information

     

    A typical Bluetooth mobile phone headset

    The latest version currently available to consumers is 2.0, but few manufacturers have started shipping any products yet. Apple Computer, Inc. offered the first products supporting version 2.0 to end customers in January 2005. The core chips have been available to OEMs (from November 2004), so there will be an influx of 2.0 devices in mid-2005. The previous version, on which all earlier commercial devices are based, is called 1.2.

    Bluetooth is a wireless radio standard primarily designed for low power consumption, with a short range (up to 10 meters [1], ) and with a low-cost transceiver microchip in each device.

    It can be used to wirelessly connect peripherals like printers or keyboards to computers, or to have PDAs communicate with other nearby PDAs or computers.

    Cell phones with integrated Bluetooth technology have also been sold in large numbers, and are able to connect to computers, PDAs and, specifically, to handsfree devices. BMW was the first motor vehicle manufacturer to install handsfree Bluetooth technology in its cars, adding it as an option on its 3 Series, 5 Series and X5 vehicles. Since then, other manufacturers have followed suit, with many vehicles, including the 2004 Toyota Prius and the 2004 Lexus LS 430. The Bluetooth car kits allow users with Bluetooth-equipped cell phones to make use of some of the phone’s features, such as making calls, while the phone itself can be left in a suitcase or in the boot/trunk, for instance.

    The standard also includes support for more powerful, longer-range devices suitable for constructing wireless LANs.

    A Bluetooth device playing the role of “master” can communicate with up to 7 devices playing the role of “slave”. At any given instant in time, data can be transferred between the master and one slave; but the master switches rapidly from slave to slave in a round-robin fashion. (Simultaneous transmission from the master to multiple slaves is possible, but not used much in practice). These groups of up to 8 devices (1 master and 7 slaves) are called piconets.

    The Bluetooth specification also allows connecting two or more piconets together to form a scatternet, with some devices acting as a bridge by simultaneously playing the master role in one piconet and the slave role in another piconet. These devices have yet to come, though are supposed to appear within the next two years.

    Any device may perform an “inquiry” to find other devices to which to connect, and any device can be configured to respond to such inquiries.

    Pairs of devices may establish a trusted relationship by learning (by user input) a shared secret known as a “passkey”. A device that wants to communicate only with a trusted device can cryptographically authenticate the identity of the other device. Trusted devices may also encrypt the data that they exchange over the air so that no one can listen in.

    The protocol operates in the license-free ISM band at 2.45 GHz. In order to avoid interfering with other protocols which use the 2.45 GHz band, the Bluetooth protocol divides the band into 79 channels (each 1 MHz wide) and changes channels up to 1600 times per second. Implementations with versions 1.1 and 1.2 reach speeds of 723.1 kbit/s. Version 2.0 implementations feature Bluetooth Enhanced Data Rate (EDR), and thus reach 2.1 Mbit/s. Technically version 2.0 devices have a higher power consumption, but the three times faster rate reduces the transmission times, effectively reducing consumption to half that of 1.x devices (assuming equal traffic load).

    Bluetooth differs from Wi-Fi in that the latter provides higher throughput and covers greater distances but requires more expensive hardware and higher power consumption. They use the same frequency range, but employ different multiplexing schemes. While Bluetooth is a cable replacement for a variety of applications, Wi-Fi is a cable replacement only for local area network access. A glib summary is that Bluetooth is wireless USB whereas Wi-Fi is wireless Ethernet.

    Many USB Bluetooth adapters are available, some of which also include an IrDA adapter.

    Embedded Bluetooth

    Bluetooth devices and modules are increasingly being made available which come with an embedded stack and a standard UART port. The UART protocol can be as simple as the industry standard AT protocol, which allows the device to be configured to cable replacement mode. This means it now only takes a matter of hours (instead of weeks) to enable legacy wireless products that communicate via UART port.

    Features by version

    Bluetooth 1.0 and 1.0B

    Versions 1.0 and 1.0B had numerous problems and the various manufacturers had great difficulties in making their products interoperable. 1.0 and 1.0B also had mandatory Bluetooth Hardware Device Address (BD_ADDR) transmission in the handshaking process, rendering anonymity impossible at a protocol level, which was a major set-back for services planned to be used in Bluetooth environments, such as Consumerism.

    Bluetooth 1.1

    In version 1.1 many errata found in the 1.0B specifications were fixed. There was added support for non-encrypted channels.

    Bluetooth 1.2

    This version is backwards compatible with 1.1 and the major enhancements include

    • Adaptive Frequency Hopping (AFH), which improves resistance to radio interference by avoiding using crowded frequencies in the hopping sequence
    • Higher transmission speeds in practice
    • extended Synchronous Connections (eSCO), which improves voice quality of audio links by allowing retransmissions of corrupted packets.
    • Received Signal Strength Indicator (RSSI)
    • Host Controller Interface (HCI) support for 3-wire UART
    • HCI access to timing information for Bluetooth applications.

    Bluetooth 2.0

    This version is backwards compatible with 1.x and the major enhancements include

    • Non-hopping narrowband channel(s) introduced. These are faster but have been criticised as defeating a built-in security mechanism of earlier versions; however frequency hopping is hardly a reliable security mechanism by today’s standards. Rather, Bluetooth security is based mostly on cryptography.
    • Broadcast/multicast support. Non-hopping channels are used for advertising Bluetooth service profiles offered by various devices to high volumes of Bluetooth devices simultaneously, since there is no need to perform handshaking with every device. (In previous versions the handshaking process takes a bit over one second.)
    • Enhanced Data Rate (EDR) of 2.1 Mbit/s.
    • Built-in quality of service.
    • Distributed media-access control protocols.
    • Faster response times.
    • Halved power consumption due to shorter duty cycles.

    Future Bluetooth uses

    One of the ways Bluetooth technology may become useful is in Voice over IP. When VOIP becomes more widespread, companies may find it unnecessary to employ telephones physically similar to today’s analogue telephone hardware. Bluetooth may then end up being used for communication between a cordless phone and a computer listening for VOIP and with an infrared PCI card acting as a base for the cordless phone. The cordless phone would then just require a cradle for charging. Bluetooth would naturally be used here to allow the cordless phone to remain operational for a reasonably long period.

    Security concerns

    In November 2003, Ben and Adam Laurie from A.L. Digital Ltd. discovered that serious flaws in Bluetooth security lead to disclosure of personal data (see http://bluestumbler.org). It should be noted however that the reported security problems concerned some poor implementations of Bluetooth, rather than the protocol itself.

    In a subsequent experiment, Martin Herfurt from the trifinite.group was able to do a field-trial at the CeBIT fairgrounds showing the importance of the problem to the world. A new attack called BlueBug was used for this experiment.

    In April 2004, security consultants @Stake revealed a security flaw that makes it possible to crack into conversations on Bluetooth based wireless headsets by reverse engineering the PIN.

    This is one of a number of concerns that have been raised over the security of Bluetooth communications. In 2004 the first purported virus using Bluetooth to spread itself among mobile phones appeared for the Symbian OS. The virus was first described by Kaspersky Labs and requires users to confirm the installation of unknown software before it can propagate. The virus was written as a proof-of-concept by a group of virus writers known as 29a and sent to anti-virus groups. Because of this, it should not be regarded as a security failure of either Bluetooth or the Symbian OS. It has not propagated ‘in the wild’.

    In August 2004, a world-record-setting experiment (see also Bluetooth sniping) showed that with directional antennas the range of class 2 Bluetooth radios could be extended to one mile. This enables attackers to access vulnerable Bluetooth-devices from a distance beyond expectation.

    Bluetooth uses the SAFER+ algorithm for authentication and key generation.

    Bluetooth profiles

    In order to use Bluetooth, a device must be able to interpret certain Bluetooth profiles. These define the possible applications. Following profiles are defined:

    • Generic Access Profile (GAP)
    • Service Discovery Application Profile (SDAP)
    • Cordless Telephony Profile (CTP)
    • Intercom Profile (IP)
    • Serial Port Profile (SPP)
    • Headset Profile (HSP)
    • Dial-up Networking Profile (DUNP)
    • Fax Profile
    • LAN Access Profile (LAP)
    • Generic Object Exchange Profile (GOEP)
    • Object Push Profile (OPP)
    • File Transfer Profile (FTP)
    • Synchronisation Profile (SP)

    This profile allows synchronisation of Personal Information Manager (PIM) items. As this profile originated as part of the infra-red specifications but has been adopted by the Bluetooth SIG to form part of the main Bluetooth specification, it is also commonly referred to as IrMC Synchronisation.

    • Hands-Free Profile (HFP)
    • Human Interface Device Profile (HID)
    • Hard Copy Replacement Profile (HCRP)
    • Basic Imaging Profile (BIP)
    • Personal Area Networking Profile (PAN)
    • Basic Printing Profile (BPP)
    • Advanced Audio Distribution Profile (A2DP)
    • Audio Video Remote Control Profile (AVRCP)
    • SIM Access Profile (SAP)

    Compatibility of products with profiles can be verified on the Bluetooth Qualification website.

    Are MIFARE and ISO/IEC 14443 Type A the same?

    MIFARE and ISO/IEC 14443 Type A are not the same. While MIFARE is often viewed as an extension to or subset of ISO/IEC 14443 Type A, it is a proprietary encryption/conditional access protocol owned and licensed by Philips Semiconductors to multiple vendors of card ICs and reader ICs.

    Because MIFARE has been so predominantly used with products employing ISO/IEC 14443 Type A technology, it has mistakenly become synonymous with the standard. However, ISO/IEC 14443 Type A is a completely open standard when used independently of the MIFARE encryption/conditional access scheme.

    Is there a risk of someone listening or stealing the information from a contactless card?

    One risk with contactless cards is the ability for the card to be activated when it enters a reader’s RF range without the owner being aware of it. To prevent a contactless card activation without the card owner being aware of it, the application can be configured to always ask for the owner’s authorisation (password, PIN or biometric) before providing any user information or processing on the user’s behalf.

     

    e level of security of communication required between the contactless card and the reader must be defined as part of the system design and security controls must put in place so that un-invited listeners cannot intercept the data in any meaningful way. For example, all of the contactless technologies can use data encryption to protect data on the card and during transmission; this helps to ensure that, if information is intercepted, the information cannot be used by the recipient. It is important that all of the application’s requirements be understood and defined prior to any technology selection and implementation so that the appropriate security features are designed into the system.
    Additionally, the contactless chip is designed to self destruct if anyone tries to hack into it.

    At the core is our Intelligent Communications Exchange (ICE) which enables all known transaction enablers from EFTPOS to eCommerce to be routed directly to a client’s bank without intervention for real time acceptance and authentication.

    The EFT Networks ICE operates under a philosophy of total System and Physical redundancy delivering the highest uptime rates possible, whilst the transaction network is protected using Solid State and Application Firewalls on all points of ingress and egress.

    Every transaction processed through EFT Networks is encrypted using 128 bit Secure Socket Layer (SSL) encryption and submitted for authorisation through EFT Networks “Secure Virtual Private Network” (SVPN).

    Our commitment to security is also reflected in our swift compliance with Card Schemes security initiatives such as VerifiedByVisa and MasterCard SecureCode.
