摘要：
In order to solve the current problem of centralized storage of electronic evidence, to meet the requirements of confidentiality and transmission security of electronic evidence, this paper uses blockchain technology and applies distributed key generation technology to ciphertext policy attribute-based proxy re-encryption (CP-ABPRE), and designs a blockchain-based multi-centered data sharing scheme. The data sharing scheme is combined with Interplanetary File System (IPFS) to proposes a model of electronic evidence sharing that can resist conspiracy attacks. By comparison and analysis, the scheme is able to achieve fine-grained access control and secure sharing of electronic evidence.
