摘要:

3G系统为代表的移动通信系统中,根密钥的管理存在缺乏更新机制或更新机制不安全的问题。本文提出了一种适用于移动通信系统的基于非对称加密的根密钥管理方案。该方案模拟了移动通信系统中根密钥的一般使用场景,通过使用PKI (Public Key Infrastructure)技术保证根密钥的安全更新。为了提高可用性,该方案改进了密钥管理流程,本文以WPKI为例分析了这些改进对方案效率的影响
>Some of current mobile communication systems represented by 3G systems do not support root key updating, others lack a secure updating method. This paper proposes a root key management scheme which is based on asymmetric encryption and can apply to most of mobile communication systems. This scheme simulates the common using scene of root key in mobile communication systems and protects the security of root key updating by PKI (Public Key Infrastructure). To improve the availability of the system, this scheme gives a modification for root key management. We analyze these improvements’ impact on the scheme efficiency taking WPKI for example.
