Group-Based Key Management for Multicast of Ad Hoc Sensor Network

摘要

In order to protect communication security among sensor nodes, a cryptographic method are needed by ad hoc sensor networks. According to that most ad hoc sensor networks are deployed in groups, a group-based multicast key management scheme is proposed to extend RPS scheme in this paper. Compared with RPS, our scheme improves the probability that a shared key exists between two sensor nodes, and reduce the probability that the shared key is decrypted.
