In order to resolve the collusion resistance problem in the one-way hash chain-based self-healing group key distribution schemes and improve the performance of previous self-healing group key distribution schemes, we propose a self-healing group key distribution scheme based on the revocation polynomial and a special one-way hash key chain for wireless sensor networks (WSNs) in this paper. In our...
Due to the characteristics of underwater acoustic channel, such as long propagation delay and low available bandwidth, media access control (MAC) protocol designed for the underwater acoustic sensor network (UWASN) is quite different from that for the terrestrial wireless sensor network. However, for the contention-based MAC protocols, the packet transmission time is long because of the long preamble...
