Architecture of Bluetooth Security for Pairing Key and Better Authentication

In this paper, we have deal with the authentication and identification of the device for higher security using key pairing and low computation. Bluetooth when start communication with other device it needs pairing, and then a number of other processes, Profile selection which defines the types of communication. The connection can be compromised and without pairing codes connection can be established. Once the connection is established passing command to the victim's device makes the device to work in favor of the attacker without being noticed by the owner of the device. One such tool is bluesnarfer which is used to pair two devices without being acknowledged by the owner or the victim. This paper is proposed for finding a solution to the same using asymmetric key cryptography and encrypted protocol values to gain access of the different function of the Bluetooth device. The solution is deployed in a number of phases. Public and private key based pairing is used which make the authentication more effective. This is the first phase. In the next second phase there will be we verification protocol in which referential connection is required for making a new connection. In the third phase information regarding profile choice is passed through a tunnel profile, which passed on to the actual profile required. This system contains a threshold function which defines that if at any stage a breach of the system is identified then the system will promote the attacker with improper information to miss lead the attacker so that either the attacker is kept stuck in a miss leading loop or the connection is closed.
