摘　　要：伴随着信息技术的高速发展和高等教育的普及,传统的中心化高校学生档案管理平台已经不能满足日益增长的需求,数字化档案系统建设已经成为一种必然趋势。传统的中心化档案管理系统存在数据容易被篡改、数据不一致、数据共享难等问题。针对这些问题,区块链技术去中心化和去信任的特性基本解决了目前数字化档案所存在的安全和信任问题,但是可用性较差、扩展性不强,并且当电子档案遭到破坏后无法恢复,难以满足档案数据共享的实际要求。本文提出一种基于代理重加密的区块链档案数据共享模型,并在此基础上设计实现了一种基于代理重加密的区块链学生档案管理系统,性能分析表明系统在加密和解密阶段的计算开销相对较小,而且执行效率相对较高,在档案数据共享场景具备一定的优势和实用性。With the rapid development of information technology and the popularization of higher educa-tion,traditional centralized college student record management platform is unable to satisfy the increas-ing demand,and constructing digital record system becomes an inevitable trend.Traditional centralized record management system has problems such as easy data tampering,inconsistent data,difficult data sharing,etc.To address these problems,the decentralization and de-trust of blockchain characteristics are utilized to basically solve the security and trust problems existing in current digital record.However,this scheme faces the issues of poor applicability,weak scalability,and hard recovery when the digital record suffering from damage,dificult to satisfy the requirements for record data sharing.In this paper,a blockchain record data sharing model based on proxy re-encryption is proposed,on which a block-chain student record management system based on proxy re-encryption is designed.Efficiency analysis indicates that this system has a relatively small computational overhead in the encryption and decryption stages and a relatively high execution efficiency,and has superiority and practical applicability in record data sharing scenario.
