Data security is an important issue in data transmission through any type of network whether it is LAN, WAN, MAN or PAN. The authors are concentrating on PAN that is personal area network. Bluetooth is an example of this type of network. To provide the security in Bluetooth communication currently used encryption algorithm is a 128 bit symmetric stream cipher but symmetric cipher may be broken under certain condition. Another popularly used encryption algorithm for Bluetooth security is Data Encryption Standard (DES) and Ron Rivest, Adi Shamir and leonard adleman (RSA) Algorithm. However DES is vulnerable to possible attacks. To overcome these limitations and increase the security in Bluetooth communication here they propose an integrated cryptographic scheme.
