一种新的基于双线性配对的移动Ad hoc网络组密钥协商方案
A NEW BILINEAR PAIRING BASED MANET GROUP KEY AGREEMENT SCHEME
摘要
Abstract
Taking secure group broadcasting communication requirements in MANET environment into consideration, how to realize a group key management scheme that on the one hand costs low and on the other hand offers enough safety and efficiency has been a problem that gains much attention. By introducing bilinear pairing of eclipse curve password mechanism, a novel efficient authenticable distributed group key management scheme is proposed. Based on BCDHP and BDLP assumptions, the scheme is further proven to be safe enough to effectively resist impersonation attacks and collusive crack attacks. The scheme bears perfect forward secrecy and backward secrecy so that it guarantees justice for group members in secure group communications. Different from other schemes, the proposed scheme achieves group key agreement after just one round, costing little on storage, communication and computation. Therefore the scheme is very suitable for resource limited MANET.关键词
