摘　　要：快递出海必然涉及快递数据的跨境交互,为了解决数据共享之下的数据出境安全问题,提出了一种基于区块链和代理重加密的快递出海数据共享方案。在具体构造上,由审核部门对出境数据进行监管并处理敏感信息,再作为数据共享的一方将第一次加密的密文发送到区块链网络中,通过代理重加密方法实现安全、隐私的数据共享。经过分析,文章方案能够保证数据的真实性与不可篡改,并能够正确地还原数据明文,在满足隐私保护的前提下实现了数据出境的安全共享。Express to sea inevitably involves the cross-border interaction of express data.In order to solve the problem of data exit security under data sharing,a data sharing scheme of express to sea based on blockchain and agent re-encryption is proposed.In terms of specific structure,the audit department will supervise the exit data and process the sensitive information,and then send the first encrypted cipher text to the blockchain network as the data sharing party,and realize the secure and private data sharing through the agent re-encryption method.Through analysis,the scheme of this paper can ensure the authenticity and tamper of the data,and can correctly restore the data,to meet the requirements of privacy protection under the premise of realizing the safe sharing of data exit.
