CP-ABE based Access Control with Policy Updating and Fast Decryption for Intelligent Manufacturing
作者 Long LiTianlong GuLiang ChangJingjing LiJunyan Qian
英文摘要
In view of the information security problems existed in intelligent manufacturing system, a system model and its corresponding CP-ABE based access control framework are presented. Moreover, a MA-CP-ABE based on Ordered Binary Decision Diagram (OBDD) is proposed to solve the common drawbacks of CP-ABE schemes, such as limited expression ability of access structure, inefficient sub algorithms, poor system reliability caused by single authority, and lack of policy updating mechanism. The proposed scheme has several remarkable characteristic. Firstly, an OBDD-based access structure is proposed to realize the efficient representation of access policies. Secondly, the sub-algorithms such as key generation algorithm and decryption algorithm have good performance. In particular, the complexity of decryption algorithm is constant, not limited to any variable in the system, which result in fast decryption. Thirdly, the reliability and stability are enhanced by the set-up of multiple attribute authorities. Fourthly, the access policy updating mechanism has better feasibility, because the adoption of proxy ciphertext updating and lazy key generation. Theoretical analysis further proofs the above superiorities of the new scheme. In addition, the new scheme is able to resist collusion attack and provide forward security and CPA security.
