5G D2D中新型防共谋密文策略属性基加密方案
Novel dynamic anti-collusion ciphertext policy attribute-based encryption scheme in 5G D2D environment
摘要
Abstract
To share data securely with secure attribute revocation,anti-collusion,and dynamic user management in the 5G device-to-device (D2D) environment,a novel dynamic anti-collusion ciphertext policy attribute-based encryption(NDA-CP-ABE) scheme in the 5G D2D environment is proposed.On the basis of the ciphertext policy attribute-based encryption algorithm,fine-grained access control and secure attribute revocation are realized,and the confidentiality of data is guaranteed.A polynomial function is adopted in the ciphertext generation phase to realize dynamic user management.A random number is used to prevent a collusion attack among the legitimate user equipment (UE),revoked UE,and external network attackers.Finally,on the basis of the Diffie-Hellman problem,the NDA-CP-ABE scheme is formally proved,and the simulation performances are compared with those of similar schemes.The results show that data can be securely shared through a D2D channel with secure attribute revocation,anti-collusion,and dynamic user management.Moreover,compared with similar schemes,the NDA-CP-ABE scheme has higher efficiency in encryption,decryption,and storage.关键词
