电力物联网下基于SM9的CP-ABE访问控制方案
SM9-based CP-ABE Access Control Scheme under Power IoT
摘要
Abstract
[Purposes]This work has been carried out to achieve fine-grained access control based on the existing power IoT.[Methods]A ciphertext policy attribute based encryption(CP-ABE)scheme for power IoT scenarios based on the SM9 algorithm was proposed.[Results]On one hand,the proposed scheme solves the key escrow problem easily caused by a single authorized author-ity by using the multi-authority management mechanism,and achieves the traceability of malicious us-ers and the direct revocation mechanism of agent-based attributes by establishing a two-level key gen-eration architecture.On the other hand,the scheme makes use of the technology of outsourcing en-cryption and decryption computation to reduce the resource consumption of power terminal equipment in terms of computation,storage,and communication.The security and performance analyses show that the proposed scheme satisfies IND-CPA security under the DBDH assumption,and the resource overhead of the terminals in the scheme is smaller and more fixed compared with that of existing schemes.关键词
