Ad hoc网络安全模型的研究

Research on Security Model in Ad hoc Networks

Ad hoc网络作为一种无线移动网络正成为网络研究的一个热点。而且由于它的若干特点 ,使得 Adhoc网络在军事领域受到广泛的重视 ,并正在逐步应用于商业领域。但安全问题却是 Ad hoc网络的一个弱点。根据 RSA密码体制和门限数字签名方案 ,提出了一种门限 RSA数字签名方案 ,并在此基础上提出了一种基于信任分散的 Ad hoc网络安全模型。该安全模型对建立一个安全的 Ad hoc网络有着一定的意义。

As wireless mobile networks, ad hoc networks have become a hot spot on network research. And much attention has been paid to Ad hoc networks in military and commercial fields because of their qualities. But ad hoc networks are vulnerable in security. In this paper, a threshold RSA digital signature scheme is put forward based on RSA cryptography and threshold digital signature scheme, and then a security model based on trust distributed policy in ad hoc networks is described in detail. This security model will be significant for creating a secure ad hoc network.
