Accelerated vBNN-IBS Authentication Scheme for WSN

Broadcast authentication is the base of network security in WSN (Wireless Sensor Network) due to versatility task and limited energy. The symmetric encryption has been widely used in WSN because of its high energy efficiency, but the network is vulnerable to DoS (Denial of Service) attacks on account of time delay during the authentication. An accelerated signature mechanism AvBNN-IBS (Accelerated vBNN-IBS), focus on the fix-deployed WSN, through the way of mutual cooperation between nodes is put forward in this paper to solve the problems of low calculation speed and complex algorithm of public key encryption mechanisms. Compared with the traditional authentication mechanisms, the scheme proposed could effectively lower the energy consumption and authentication time.
