Retail logistics privacy protection model in the blockchain environment
Traditional retail logistics may expose customers' privacy information.To address the problem, the proxy re-encryption is widely employed, but a malicious node may exist in the proxy node.In this paper, a retail logistics model based on blockchain and proxy re-encryption is proposed.It employs blockchain, proxy re-encryption and interplanetary file system to effectively prevent the leakage of users' privacy information.Meanwhile, the model designs a reward and punishment mechanism for proxy nodes to prevent a malicious one from occurring.When blockchain nodes become proxy nodes, they need to pledge the tokens stipulated in the contract.If the proxy node is honest, it will obtain the token reward according to the contract.Our experimental results show the model realizes the logistics process under normal overhead.A performance analysis demonstrates the proposed algorithm performs better in both encryption and decryption compared with other schemes.
