摘要
随着第五代移动通信(Fifth Generation:5G)技术标准的完善,5G在各个领域受到前所未有的关注,然而5G依然面临一些安全挑战。针对5G终端的接入安全和数据安全问题,指出合适的密码技术解决方案。对于接入认证问题,可以采用无证书密码体制、基于同态加密的数据聚合机制,以及基于身份的聚合签密等密码技术来解决。对于数据存储和共享安全问题,可以采用属性基加密和抗密钥泄露技术来解决。随着5G的商用,上述密码技术与5G安全研究将具有重要的理论与实际意义。
With the improvement of technology standards of the fifth generation(5G)mobile communication,5G has received unprecedented attention in various fields.However,many security challenges remain in 5G.To address the access security and data security issues of 5G terminals,the appropriate solutions based on cryptographic technology are specified.As for the access authentication problem,some cryptographic technologies can be adopted,such as certificateless cryptography,data aggregation mechanisms based on homomorphic encryption,and identitybased aggregation signcryption.For the security problems of data storage and sharing,attribute-based encryption and leakage resilience techniques can be exploited.With the commercialization of 5G,the above cryptography and 5G security research will be of theoretical and practical significance.
