摘　　要：随着云计算的发展,在加密的云数据上进行隐私保护的关键字查询是近年来学术界研究的热点。目前已有的方案很少考虑多数据查询用户场景下的新用户注册和过期用户撤销问题。针对这一问题,本文提出了一种高效的多数据查询用户环境下的云安全查询方案。通过设计安全索引、查询限门以及安全匹配算法,提出的方案不仅实现了密文环境下高效的关键字查询,而且支持灵活的新用户注册和过期用户撤销操作。大量实验表明,我们的方案是正确和高效的。With the rapid development of the cloud computing,the privacy-preserving keywords search over encrypted cloud data becomes a hot research topic.Few existing works consider the important issues of the new user enrollment and the expired user revocation to or from the search system in the multi-user environment.This paper proposes an efficient multi-user secure search scheme over encrypted cloud data.By skillfully designing secure indexes,query trapdoors,and the matching algorithm between the secure index and the query trapdoor,the proposed scheme not only achieves efficient keyword-based search over encrypted data,but also supports effective new user enrollment and expired user revocation operations.Extensive experiments demonstrate that the proposed scheme is correct and efficient.
