摘　　要：密文策略属性基加密(CP-ABE)技术是目前智能电网中访问控制研究的重点和难点,但常规CP-ABE方案中,存在访问策略泄露用户隐私、计算量大、效率低等问题。针对这些问题,提出智能电网中高效可撤销的属性基访问控制方案。采用在线/离线加密和外包解密,提高系统的效率;采用变色龙哈希函数,实现安全的用户和属性撤销。安全性分析和性能分析证明了方案的安全性和计算优势。Ciphertext policy attribute-based encryption(CP-ABE)technology is the focus and difficulty of access control research in smart grid.However,in the conventional CP-ABE scheme,there are some problems such as access policy divulging user privacy,large amount of computation and low efficiency.To solve these problems,an efficient and revocable attribute-based access control scheme for smart grid is proposed.Online/offline encryption and outsourcing decryption were used to improve the efficiency of the system.Chameleon Hash function was used to realize safe user and attribute revocation.Security analysis and performance analysis proved the security and computing advantages of the scheme.
