基于ATP-ABE的访问控制方案
Access Control Scheme Based on ATP-ABE
摘要
Abstract
To research the security and efficiency of the access control mechanism, this paper proposes an access control scheme based on the ATP-ABE(Access Tree Pruning Attribute Based Encryption). When the ATP-ABE algorithm requires its access tree structure of the access policy, it prunes the access tree’s branch which contains the user ID attribute node. It can not only improve the DO’s efficiency of attribute management and control, but also be easy to realize data sharing. Meanwhile it designs the permission access attribute for access tree structure. The DO still retains the key attributes of shared data and can control their shared data completely. The DBDH(Decisional Bilinear Diffie-Hellman)assumption ana-lyzes the security of the ATP-ABE scheme. The results show that compared with the two classical ABE scheme, the ATP-ABE can reduce the system settings, the private key generation, the ciphertext size, the user attribute revocation, the encryp-tion and decryption in the computational overhead, and it gives a quantitative conclusion of the algorithm.关键词
