A Secure Anonymous Path Routing Protocol for Wireless Sensor Networks

recently, how to support secure anonymous communications in resource restricted wireless sensor network has became the hot topic. In this paper, a secure anonymous routing protocol for wireless sensor network is proposed based on bilinear pairing and exclusive or operation, the protocol not only can provide routing anonymity, location privacy and the identity confidentiality of source node and destination node, but also has the backward and forward security. In this protocol, the symmetric secret key substitute for the asymmetric secret key, and the exclusive or operation substitute for the mould exponent operation, the protocol improves distinctly in computation, and is more suitable for the wireless sensor network.
