According to the existing problems in current key management strategy of wireless sensor network, which have computation complexity, multi-memory space and inflexible management, this paper proposed a mixed key management scheme of clustering wireless sensor network. Implementing the LU matrix decomposition in the cluster heads communication and Chinese remainder theorem in sensors communication,...
This paper improves an authentication protocol based on The Elliptic curve Cryptography, and applies it to WSNs. This scheme contains system initialization, node registration and authentication phase. It continues to use the primary scheme's high efficient multiplication operation method, and the sensor node store the other ID's hash value as the premise of the authentication. Besides, this scheme...
