有很多数据管理系统，基于各种原因，将它们的高计算工作量指定给公共云服务提供商。众所周知，一旦我们将任务委托给云服务器，就可能面临多种威胁，如用户属性信息的隐私侵犯，因此，构建安全的云数据管理系统(SCBDMS)必须有合适的隐私保护机制。即使服务器工作在诚实但好奇的模式下，设计一个具有服务器强制撤销能力的可靠的SCBDMS也是一项非常具有挑战性的任务。在现有的数据管理系统中，很少提供隐私保护的撤销服务，特别是在将其外包给第三方的情况下。借助于不经意传输和新提出的无状态惰性重加密(SLREN)机制，构建了一个具有安全、可靠和服务器强制属性撤销能力的SCBDMS。实验结果表明，与相关工作相比，在新构建的SCBDMS中，由于SLREN的后期介入，云服务器的存储需求以及云服务器与系统用户之间的通信开销大大降低。
There are lots of data management systems, according to various reasons, designating their high computational work-loads to public cloud service providers. It is well-known that once we entrust our tasks to a cloud server, we may face several threats, such as privacy-infringement with regard to users attribute information; therefore, an appropriate privacy preserving mechanism is a must for constructing a secure cloud-based data management system (SCBDMS). To design a reliable SCBDMS with server-enforced revocation ability is a very challenging task even if the server is working under the honest-but-curious mode. In existing data management systems, there seldom provide privacy-preserving revocation service, especially when it is outsourced to a third party. In this work, with the aids of oblivious transfer and the newly proposed stateless lazy re-encryption (SLREN) mechanism, a SCBDMS, with secure, reliable and efficient server-enforced attribute revocation ability is built. Comparing with related works, our experimental results show that, in the newly constructed SCBDMS, the storage-requirement of the cloud server and the communication overheads between cloud server and systems users are largely reduced, due to the nature of late involvement of SLREN.
