Security in Bluetooth Wireless Technology

Bluetooth Wireless Technology is one of the most commonly followed wireless data transfer process followed in the Information Technology sector. Any data transfer system or any communication and connection system first of all demands security. If the various parts of a Universal Serial Bass (USB) engaged in the data transfer process are not brought under tight security, there are enough chance of data leakage. To prevent this leakage every measures have been adopted to enhance security in Bluetooth Wireless Technology.
Security in Bluetooth Wireless Technology offers authentication, confidentiality and also an effective derivation of the keys by the use of custom algorithms which works on the basis of SAFER+ block cipher. Key generation is a very important feature of security in Bluetooth Wireless Technology. In this kind of Universal Serial Bass (USB) the security key is generated by the use of a key. This key generation is done on the basis of a Bluetooth PIN. This typical Bluetooth PIN is to be entered into both the master computer and also in the slave computer. This process of Bluetooth PIN often becomes modified a bit in many computers when one of the connecting devices receives a fixed PIN. Devices. It often happens that the headsets or other likely devices like headsets use a fixed PIN. But first of all a key making the initialization process of the Universal serial Bass (USB) possible. This special key selected for the purpose of initialization of the functioning of Bluetooth is called master key or initialization key.

Security in Bluetooth Wireless Technology was very essential as it has been found by Ben and Adam Laurrie of A.L. Digital Ltd. in the November of the year 2003 that data stored in the computer or in any cellphone can be leaked out due to some serious flaws in the security system of the Universal Serial Bass (USB), Bluetooth. After that all sorts of efforts have been taken to ensure and enhance the level of security in Bluetooth Wireless Technology.

Encryption of different devices installed in the Bluetooth is done by E0 stream cipher which is used giving confidentiality and also for encryption of different packets. This E0 stream cipher security system is run on a shared cryptographic system. This E0 stream cipher system is actually an already made master key or link key. These link keys or master keys which are used for encryption of data transmit data using the air interface. The unique fact about these keys used in the operation of this Universal Serial Bass (USB) is that these keys do not rely on the use of the PIN of Bluetooth which has already been in both the devices connected with each other or in any of the devices.

Bluejacking Bluejacking is a very useful mean to send cards meant for business without disclosing the name of the senders. Senders can send these anonymous business cards using the Bluetooth technology from their cellphone. Bluejacking does not need the replacement or change of any data from the devices used for sending cards.
