Abstract：In order to improve safety certification of wireless sensor networks, a new scheme is proposed based on a shared key mutual authentication and key agreement, including registration phase, login phase, authentication and key agreement stage. The registration phase is to complete registered user node A and the sensor node S, and store the user node A pseudo-identity ID: , the pseudo-identity information , hash function and the sensor nodes S identity . In the login phase, the user enters a smart card with the identity IDA and signature to obtain identity information . The authentication and key agreement phase is completed using mutual authentication and shared key. Compared with other schemes, the proposed scheme provides anonymity to avoid a simulated attack user, nodes, and can avoid replay attack, middle attack, DoS attacks, to improve the network security. In terms of computational overhead, the execution time of the program is about 0.42 ms, compared with similar programs to reduce the amount of computation.
