This paper studies the improvement and implementation of access control method under ABAC model in detail. By further analysis of encyption principle and algorithm implementation process, and contrast on mainstream ABE algorithms, it selects CP-ABE as access control algorithm for security and performance, to be used in ABAC access control model under cloud computing environment. We improve the algorithm and optimize the system to reduce the computation during access control process. So it can well integrate with ABAC model to protect the privacy of information resource. The tests show the improved scheme has rapid speed in encryption/decryption with ABAC model, and needs smaller storage space, which is also a better encryption mechanism for cloud environment.
