移動(dòng)通信用戶身份保密的增強(qiáng)方法
The Enhanced Methods of User Identity's Confidentiality in Mobile Communication

摘要: 針對(duì)現(xiàn)有移動(dòng)通信標(biāo)準(zhǔn)中無法完全實(shí)現(xiàn)用戶身份保密這一問題,該文提出了分別基于公鑰密碼學(xué)和對(duì)稱密鑰密碼學(xué)的兩種改進(jìn)措施,將用戶的真實(shí)身份隱蔽在眾多的用戶標(biāo)識(shí)里,使攻擊者不能確切地得到用戶身份的具體信息,明顯增強(qiáng)了用戶身份的保密性,并且分析比較了兩種措施的性能.這些改進(jìn)措施可以用于任何移動(dòng)通信技術(shù)中.Abstract: 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.
