摘要
Nodes in a sensor network may be lost because of power exhaustion or malicious attacks. Therefore, new node deployment is necessary. Based on elliptic curve cryptography (ECC), this paper presents a new access control protocol for secure wireless sensor networks. The authentication procedure and common key generation are very simple and efficient. It is quite adequate for power and resource constrained sensor nodes. In addition, the proposed scheme can be easily implemented as a dynamic access control because all the old secret keys and broadcasting information in existing nodes should not be updated once a new node is added.
