摘　　要：移动节点组成移动自组网(MANETs),MANETs没有固定的网络基础设施,也不存在中心信任机构,密钥管理是移动自组网安全最核心、最困难和最薄弱的环节,为了降低PKG密钥管理方案的通信开销,论文将ElGamal方案与预分配密钥管理方案相结合,提出了一种基于身份的预分配非对称密钥管理方案,在一定程度上降低了移动ad hoc网络非对称密钥管理中的通信开销[1~2],提高了网络安全。Mobile ad hoc network(MANETs)is composed of mobile nodes,without fixed network infrastructure and central trust agencies.Key management is the core,most difficult and weakest link of mobile ad hoc network security.In order to reduce the communication overhead of typical ID-based distributed threshold PKG key management scheme,this paper combines ElGamal scheme with pre-distributed key management scheme,and proposes an identity-based pre-distributed asymmetric key management scheme.Hoc network is reduced on a certain procedure,and the network security is improved.
