一种基于三方密钥协商的移动IP注册协议

目前大多数移动IP注册协议都是采用对称密码体制和基于公钥密码体制相结合的方式来实现移动实体之间的相互认证,移动节点和外地代理之间没有认证,存在一定的安全缺陷。针对这种移动IP注册协议的认证安全问题,将无证书的三方密钥协商方案引入到移动IP的注册,提出了基于三方密钥协商的移动IP注册协议,实现移动节点、家乡代理和外地代理这三个实体的相互认证。分析结果表明,协议具有更高的安全性,且拥有较高的效率。

Mobile IP registration protocol based on tripartite key agreement

Most mobile IP registration protocols use symmetric cipher systems and public key cryptosystems together to achieve mutual authentication between entities. But these protocols have certain safety defects because there are no authentication between mobile nodes and foreign agents.In order to improve the security of mobile IP registration agreement, in this paper a certificateless tripartite key agreement (CL-TKA) is introduced into mobile IP registration.A new mobile IP registration protocol is proposed based on CL-TKA to achieve mutual authentication between mobile nodes,hometown agents and foreign agents.The analysis of this protocol shows that the proposal provides higher security and efficiency.
