摘要:

现有方案将关键词搜索加密和属性基加密相结合,解决了云环境下访问控制问题,但是未充分考虑信道安全以及关键词猜测攻击等安全问题。针对上述问题,提出了一种指派搜索服务器的关键词搜索属性加密方案,实现了关键词搜索访问权限控制,且检索不需要安全信道,可抵抗离线/在线关键词猜测攻击。实验结果表明,方案性能方面可取得较好结果,可应用于云环境。

关键词: 可搜索加密, 属性基加密, 关键词猜测攻击, 安全信道

Abstract:

Recently,some schemes combined keyword searchable encryption with attribute based encryption,solved access control problem in cloud environment,but they didn’t consider security problems like keyword guessing attack and security channels,so they couldn’t be applied to cloud.A keyword searchable attribute based encryption scheme with a designated tester was proposed,which could be against online/offline keyword guessing attacks and without security channel.Moreover,the user was able to encrypt data by setting a fine-gained access control policy.The efficiency of the scheme is analyzed it can be applied to cloud.

Key words: searchable encryption, attribute based encryption, keyword guessing attack, secure channel
