Elliptical Curve Cryptography Based Hop-Hop Message Authentication
Devi Radhakrishnan
Abstract: Sensor networks are implemented in those environment which are always unattended. Thus these networks become vulnerable to intruders. Many standard authentication schemes are implemented to prevent these attack. To reduce the unauthorized attack and malicious access from being forwarded in wireless sensor network message authentication is one of the prominent technique. Many of these techniques are based on symmetric key cryptography and public key cryptography. This method has high computational overhead, lack of scalability and resilience to node attack. To overcome this advantage in this paper we proposed a source anonymous message authentication scheme (SAMA) based on modified elliptic curve digital signature scheme. This method is better than polynomial based scheme and modified Elgamal signature method (MES). This method allows no threshold to the message transmitted.
