融合代理重加密和零知识证明的USB Key联盟链追溯系统
An Alliance Chain Traceability System for USB Key Based on Proxy Re-encryption and Zero-knowledge Proof
摘要
Abstract
At present,blockchain-based information traceability solutions are widely applied in the Internet of things(IoT)space.However,during the storage and query processes in blockchain-based traceability solutions,there is a risk of data and user privacy leakage.To address these issues,this paper proposes a trusted traceability solution for USB Keys based on consortium blockchain,integrating proxy re-encryption and zero-knowledge proof technologies.Firstly,the Interplanetary File System(IPFS)and proxy re-encryption technologies are introduced during the on-chain storage process on the blockchain to establish a secure and efficient information storage mechanism for the participating parties.Additionally,during data query,a zk-SNARK zero-knowledge proof mechanism is employed for user identity authentication and rights confirmation,ensuring the privacy of user identities in the traceability data query process.Finally,based on the proposed trusted traceability solution,a USB Key information traceability prototype system is implemented using the Hyperledger Fabric distributed ledger technology.Experiments demonstrate the feasibility of this system,effectively protecting user privacy under the premise of permission allocation and ensuring the confidentiality and authenticity of traceability information in the USB Key system.关键词
