摘要
En 中文
Nodes in a sensor network may be lost because of the power exhaustion problem or malicious attacks. Thereby new node deployment is necessary in the sensor network. Huang recently proposed a novel access control protocol (NACP) based on the elliptic curve cryptography and the hash chain. She claimed that NACP can easily add new nodes and can resist against various known attacks. However, this paper addresses that her NACP is insecure to the replay attack and against an active attack, and has the lack of hash chain renewability, which is one of the necessary aspects in the sensor network with memory restricted nodes. To cope with them, we propose an enhanced novel access control protocol which is quite adequate for power and resource constrained sensor networks(1).
