一种支持动态验证的可搜索代理重加密方案
A Searchable Proxy Re-encryption Scheme Supporting Dynamic Verification
摘要
Abstract
Traditional searchable proxy re-encryption schemes typically assume that cloud servers are honest-but-curious,an assumption that is not applicable in real-world scenarios.Therefore,this paper designs a Dynamic Verifiable Searchable Proxy Re-encryption Scheme.The scheme employs a three-layer counting Bloom filter to reduce users'query costs and support deletion operations.Additionally,blockchain technology is introduced to verify search results,and an innovative verification tag leveraging the XOR property is proposed to further enhance the flexibility of the verification process.Furthermore,by exploiting the tamper-proof characteristics of blockchain,the scheme ensures the fairness and credibility of the verification process.Experimental comparisons and security analysis confirm the feasibility and security of the proposed scheme.关键词
