摘要：Securing the broadcast in wireless sensor networks (WSNs) is crucial due to a wide range of possible attacks in addition to the limited resources in sensor node. Many public-key based solutions have been proposed to address the authentication problem in WSN. Unfortunately the slow in signature verification process cause many weaknesses related to the delay and power consumption. Additionally, the dependency on the base station in the certifying the public keys leads to one failure point and bottle neck problem. Also, the node near the base station will take additional role to reroute the packets to the base station which consume their limited power. In this paper we present a new idea that utilizes the signature-based broadcast authentication to accelerate the signature verification and minimize the base station dependency by allowing sensors sign on other sensor public key.
