Efficient Cryptographic Access Control Protocol for Sensitive Data Management

--In view of sensitive data management, an efficient cryptographic access control scheme is proposed. Based on attribute-based encryption, the proposed scheme not only inherits flexibility and fine-grained access control for users, but also realizes cryptographic management for servers. In additional, the scheme alleviates the administering burdens on the server, and handle dynamic access policies in a more efficient and cryptographic way. Compared with the existing system, the scheme relieves the server from intense encryption /decryption processing, and achieves reliable decentralized encryption /decryption with good scalability and efficiency.
