无线自组网络中分布式安全机制模型研究

Distributed CA Model in Ad hoc Network

无线自组网作为自组织网络具有极大的灵活性,很多情况下有重要的用途,但是也因为其较大的灵活性,使得网络中的认证比较困难,该文结合RSA和门限签名方案论述了一种基于门限RSA签名方案的分布式CA模型,阐述了详细的颁发证书过程并分析了系统的安全性。该模型解决了在Ad hoc网络中认证困难的问题,较之由单个实体提供认证服务大大提高了安全性能。

Abstract style As Ad hoc has great flexibility;it has important uses under a lot of situations.But also because its bigger flexibility,make the authentication in the network difficult.This article described a distributed CA model based on RSA threshold signature scheme which combined RSA and threshold signature scheme,explain the course of distribute certificates and analyze the security of the system.This model solved the problem that authentication is difficult in Ad hoc network,improving safe performance greatly compared with offering authentication by individual entity.
