Research of ABAC mechanism based on the improved encryption algorithm under cloud environment

Abstract

To solve the data security problem based on the Attribute Based Access Control (ABAC) mechanism, an improved CP-ABE algorithm which is applicable to ABAC environment is proposed. The research is done from two aspects of access system structure and formal definition to study the ABAC mechanism. Then the formal definition of improved algorithm is given. The simulation and performance analysis is also finished. The algorithm has less storage consumption and higher efficiency under ABAC environment through the comparison with traditional CP-ABE algorithm.
