摘要
战地网络容易受到攻击和破坏,如何实现未来战地网络中的安全通信是一个亟待解决的问题。提出了一种支持未来多层无线异构adhoc战地网络安全通信的安全体制,它具有如下性质:(1)可以在有/无基础网络设施模式下工作并无缝切换;(2)采用集中式CA签名和(t,l)门限签名体制相结合的认证方法;(3)对报文和报头分别加密;(4)可以对签名者的身份进行追踪。
Security is a critical problem since the tactical network infrastructur e is vulnerable to various attacks an d de-structions.A secure scheme was prop osed for the future multi -level hete rogeneous wireless ad hoc tactical network.In infras-tructure mode,the CA generates a valid signature.When the CA fails,the s ystem seamlessly switches to the inf rastructure less mode and any t ground nodes can cooperate to generate a valid group signatu re.It encrypts the body and head of th e message respectively.In addition,it can tr ace the identities of the actual sign ers.
