移动IP注册过程中主密钥分发方案研究

The solution to master key generation for mobile IP registration

移动IP注册过程的安全,主要是通过认证和消息完整性保护实现的,因此,密钥的安全有效分发便成为保证注册过程安全的关键。根据注册过程中的密钥要求,提出了基于Diffie-Hellman密钥协商机制和椭圆曲线密码算法的主密钥分发方案,并运用SVO逻辑对该方案进行了安全性分行。分析结果表明,该方案实现了密钥分发过程中双方的身份认证以及密钥的确认性和新鲜性。

Authentication and message integrity axe usually used to secure the mobile IP registration. In the process,master key generation is the key factor of registration security. By analyzing the requirements for master key generation in mobile IP registration, we proposed a solution to master key distribution based on Diffie-Hellman key generation mechanism and elliptic curves cryptography （ECC）, and used SVO logic to analyze the security of scheme . The analysis shows that the solution could accomplish the certification of identity, and bring the key to be committed and to be freshly.
