A Support Multi-user Revocable Attribute-based Lightweight Ciphertext Retrieval Scheme
摘要
Abstract
With the rapid development of cloud computing,the demand for ciphertext retrieval on the cloud has been increasing.However,traditional ciphertext retrieval schemes struggle to efficiently implement fine-grained access control in multi-user environments and face challenges such as high computational overhead and inflexible management of user attribute permissions.Therefore,this paper proposes a multi-user revocable attribute-based lightweight ciphertext retrieval scheme.Firstly,to reduce the computational burden on users,intensive computations are outsourced to a proxy server,enabling lightweight local operations.Secondly,the scheme integrates attribute-based encryption and searchable encryption to achieve efficient fine-grained access control in multi-user environments.Lastly,the scheme incorporates blockchain technology to ensure a transparent and immutable revocation process,enabling flexible and trustworthy user attribute management.Security analysis demonstrates that both user privacy and cloud-stored data are effectively safeguarded.Performance analysis indicates that the proposed ciphertext retrieval scheme is efficient and feasible for practical applications.关键词
