摘要:

为了提高门限群签名在5G环境下的安全性和效率,提出一个新的解决方案。核心思想是通过引入消息令牌和动态身份,提高认证信息的新鲜性,加大敌手攻击难度;同时精简参与各方的交互次数,并将部分计算任务迁移至服务器,减少成员部分计算开销。经过安全分析,所提方案可抵抗包括重放攻击在内的多种攻击;经过性能分析,所提方案比同类方案减少了两次与可信中心的交互,签名占用空间缩小30%,具有更短的执行时间,适用于5G网络下的资源受限设备。

关键词: 门限群签名, 5G网络, 轻量级, 重放攻击

Abstract:

In order to improve the security and efficiency of threshold group signature in 5G environment,a new scheme was proposed.The core idea was to introduce message token and dynamic identity to improve the freshness of authentication information and increase the difficulty of enemy attacks.At the same time,the number of interactions between the participating parties was simplified,and some computing tasks were migrated to the server to reduce the computing overhead of the member part.After security analysis,the proposed scheme can resist multiple attacks including replay attack.After performance analysis,the proposed scheme can reduce the interaction with the trusted center twice compared with similar schemes,reduce the signature space by 30%,and have shorter execution time,which is suitable for resource-constrained devices under 5G network.

Key words: threshold group signature, 5G network, light weight, replay attack
