Abstract :
In order to solve the problems that sensor node-key leaking and adversaries make compromised nodes as their collusions to launch new attack, the paper proposed an efficient anti-collusion scheme based on elliptic curve cryptography for wireless sensor networks. In the proposed scheme, the group-key distribution strategy is employed to compute the private key of each sensor node, and the encryption and decryption algorithms are constructed based on elliptic curve cryptography. The command center (node) only needs to broadcast a controlling header with three group elements, and the authorized sensor node can correctly recover the session key and using it to decrypt the broadcasting message. Simulation and analysis of the proposed scheme show that the proposed scheme can resist the k-collusion attack arouse by adversary or compromised nodes efficiently.
