基于CPK的Ad_hoc网络身份认证方案

Authentication Schedule of Ad_hoc Networks Based-on CPK

目前,基于门限共享加密技术的分布式CA认证方案已经提出,应用于Ad_hoc网络可提高网络的安全性。但仍要求CA在线运行,对服务节点的能力要求也较高。该文介绍了CPK算法原理,提出了基于CPK的用于移动Ad_hoc网络的认证方案。该方案可节约网络带宽资源,降低节点的处理能力要求,使认证协议简化。

So far, distributed CA Security Authentication Schedules based-on threshold cryptosystem for Ad_hoc Networks have been proposed, which could improve high security but still required on-line CA and high qulitity of server nodes.In this paper,we introduced the principle of CPK algorithm and then proposed a new authenticatin schedule for Adhoc Networks based-on CPK.By this schedule ,bandwidth resource can be saved;requirement in computational power of mobile nodes can be reduced; authentication protocol can be simplified.
