Utilization of ID-based Proxy Blind Signature Based on ECDLP in Secure Vehicular Communications
Sundram Prabhadevi, A.M. Natarajan · 2013
Security of Vehicular Ad Hoc Networks (VANETs) has been a major research area in both academia and industry. Reducing cost of computation, effective consumption of limited resources and providing uncompromised security has always been a challenge in vehicular communications. Security establishment with no certificates and/or certificate revocation gives lesser signature overhead. A novel approach using ID-based cryptosystem and proxy blind signature based on Elliptic Curve Discrete Logarithm Problem (ECDLP) over VANETs has been proposed. The security of the proposed scheme is dependent on ECDLP which takes full exponential time. The proposed mechanism provides confidentiality, integrity of the message; with low computational cost over the networks. The privacy of the user is protected by using proxy blind signature. The result shows that signature payload has been reduced thereby improving the network performance.
