Security and performance analysis of identity based schemes in sensor networks

Security and efficient data transmission without any hurdles caused by external Attackers is an issue in sensor networks. This paper deals with the provision of an assured efficient data transmission in the sensor networks. To ensure this requirement Hash based Message Authentication Code (HMAC) and Message Digest (MD) is envisaged by employing identity based digital signature scheme (IBS). Identity based scheme is an encryption scheme that generates an operation of developing secret code with secret key that protects the data during transmission without any cryptanalysis. To achieve the above requisite the modalities used in HMAC and MD5 which simulates the functional efficiency &security of data transmission in sensor networks.
