Analysis and design of secure VANET by detection and avoidance of blackhole attack

Abstract Transmission of the data and information over Ad-Hoc network and its security is a very big challenge. VANET Networks have evolved for helping mobile services, but still the users are facing lot of challenges to preserve the security of information. The proposed research includes the concepts of detecting the Blackhole node and counters it in the VANET network for preserving the network strength as well as performance using a new protocol. The proposed protocol encrypts and decrypts the information using RC4A and simultaneously protects the network from Blackhole Attack.
