摘　　要：为提高军用AdHoc网络的安全性与可靠性,提出一种分层的网络体系架构。基于时间戳的直接密钥交换签密(DKEUTS)方案,采用随机数替代时间戳,设计一种简化的基于随机数的签密(SRS)方案。根据不同层次节点的安全性需求以及通信和计算性能,选择DKEUTS方案或不同签密参数的SRS方案。通过网络割点判别,对网络连通度进行预测,重构网络拓扑,保障网络的可靠性。性能分析结果表明,该分层网络架构与安全协议可适用于节点非同构网络。In order to improve the security and reliability of military Ad Hoc network,this paper proposes a hierarchical network architecture and designs a Shortened Random-based Signcryption (SRS) scheme by using a random number instead of timestamp in Direct Key Exchange Using Timestamp Signcryption (DKEUTS) scheme.According to the security requirements,communication and computing performances of different nodes,this paper chooses the DKEUTS scheme or the SRS schemes with different signcryption parameters.By discriminating whether the network node is a cut-vertex,the network connectivity is predicted.The information of network connectivity can be used to reconstruct network topology and guarantee network reliability.Performance analysis results show that the proposed hierarchical network architecture and security protocol can be applied in node non-homogeneous networks.
