Data security is an important issue in data transmission through any type of network whether it is LAN, WAN, MAN or PAN. We 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 are Data Encryption

To overcome these limitations and increase the security in Bluetooth communication here we propose an integrated cryptographic scheme. This scheme is based on Triple DES, RSA and MD5.Triple DES algorithm (variant of DES) is used for encryption, which is more secure in comparison to DES. RSA is used to encrypt the key of triple DES. Message digest Algorithm MD5 is adopted in this mechanism to verify the integrity of the message. Three major security principles such as authentication, confidentiality and integrity are achieved together using this scheme.
