摘要:

提出了一个实现组织集合交集认证策略的新型组织隐藏的密钥协商协议,2个匿名用户从属的组织集合存在交集且元素个数至少为一个门限值时可以完成一次成功的秘密认证和密钥协商,同时保证集合交集之外的组织信息机密性。新协议在随机预言机模型下可证安全,并且在计算和通信性能上仍具备一定的优势。

关键词: 组织隐藏, 认证密钥交换, 秘密握手, 集合交集, 可关联性

Abstract:

A new affiliation-hiding authenticated key agreement protocol was proposed.The proposal enables two anonymous users to accomplish a successful secret authentication and key agreement when their groups set intersection is non-empty and the cardinality of the set intersection should not be less than a threshold value.Meanwhile,the affiliations of groups outside of the set intersection remain confidential.The proposal is provably secure under the random oracle model,and the performance of the scheme is still competitive.

Key words: affiliation-hiding, authenticated key agreement, secret handshakes, set intersection, link ability
