The Enhanced Methods of User Identity''''s Confidentiality in Mobile Communication
移动通信用户身份保密的增强方法

Focused on the scenario that none of the current standards achieves user identity's confidentiality, two enhanced methods are proposed, respectively based on public key cryptography and symmetric key cryptography, in which each user's real identity is concealed among many users' identities. So attackers can not capture the concrete identity information and user identity confidentiality is improved obviously. The performance of the two methods is analyzed and compared. And the proposed methods can be used in other mobile communication technologies.
