Puncturable Ciphertext-Policy Attribute-Based Encryption Scheme
摘要
Abstract
To address the shortcomings of traditional forward-secure attribute-based encryption(ABE)scheme in terms of practical availability and private key update efficiency,a puncturable ciphertext-policy attribute-based encryption(P-CP-ABE)scheme is proposed.Firstly,the syntax and security model of P-CP-ABE based on the idea of puncturable public-key encryption are presented.Then,a concrete P-CP-ABE scheme based on a Bloom filter is constructed.Under the decisional l-BDHE(l-Bi-linear Diffie-Hellman Exponent)assumption,the proposed scheme is proven to achieve selective for-ward security in the standard model.The performance analysis and simulation results demonstrate that private key update efficiency is significantly improved and more practical fine-grained forward security is realized by using the scheme.An efficient and secure approach for data encryption and fine-grained access control is provided by using the proposed scheme.关键词
