Research on Access Control during Search Encrypted Data

摘要：

As cloud storage becomes prevalent, more and more sensitive data is stored in the cloud storage system. In order to protect data privacy data always encrypted stored, which makes effective data utilization a very challenging task. In this paper we first introduce the concept of cloud storage, and the architecture of cloud storage. Then we introduce three classic encrypted data search methods: Linear search algorithm, security index method and then public key encryption with keyword search. Above these, we discuss three searching encrypted data approaches that can used in large cloud storage environment supported access control. These approaches are IPU (Index-Per-User), CSI (CentralSingle-lndex) approach, and RBAC (Role-Based-AccessControl) approach. And then we analyze both the advantage and disadvantage of these approaches about both the performance and security.
