基于身份的跨域分层访问控制加密方案
Cross-Domain Hierarchical Identity-Based Access Control Encryption Scheme
摘要
Abstract
Access control encryption enforces read and write permissions,and it blocks all subliminal channels that are not allowed through a sanitizer that knows neither the plaintext,senders,receivers,nor the access control policy.In view of the heavy burden of key management for the key generation center in access control encryption,this paper proposes a cross-domain hierarchical identity-based access control encryption scheme.Firstly,based on the hierarchical identity-based broadcast encryp-tion scheme,a sanitizable hierarchical identity-based broadcast encryption scheme compatible with the aggregator is proposed.Furthermore,a general construction of cross-domain hierarchical access control encryption is proposed by combining the structure preserving signatures,non-interactive zero-knowledge proof and aggregator.Then a security proof of the general construction is presented,i.e.,the no-read and no-write rules are satisfied.In addition,the general construction is instantiated to achieve semi-static security and constant ciphertext size.Finally,the performance of the instantiation scheme is analyzed.The results show that the scheme achieves many functions while ensuring efficiency.关键词
