发明内容 我们考虑加密云存储的访问控制和加密关键字搜索问题，以便它们可以针对多用户设置来实现。我们的细粒度访问控制感知多用户安全关键字搜索方法相互依赖地协调了访问控制和加密关键字搜索这两个安全概念。由于云服务器的搜索空间缩小到用户的可解密子集，所提出的方案既减少了信息泄漏，又通过我们的对比性能模拟结果证明是有效的。
SUMMARY We consider the problems of access control and encrypted keyword search for cryptographic cloud storage in such a way that they can be implemented for a multiple users setting. Our fine-grained access control aware multi-user secure keyword search approach interdependently harmonizes these two security notions, access control and encrypted key-word search. Owing to the shrinkage of the cloud server’s search space to the user’s decryptable subset, the proposed scheme both decreases information leakage and is shown to be e ffi cient by the results of our contrastive performance simulation.
