基于区块链技术的可信域扩展
Blockchain-Based Trusted Domain Expansion
摘要
Abstract
Trusted computing 3.0 relies on a trusted root based on proprietary hardware and adopts a dual architecture combining computation and protection to implement proactive immune defense.However,this approach limits the trust to a single machine and cannot extend trust across a network.This paper proposes a blockchain-based trusted domain exten-sion(BTDE)solution,leveraging blockchain's decentralization,immutability,and traceability.The solution hashes the factory measurement values of the local node's feature files again,packages them as a trusted root on the blockchain,and generates an asymmetric key for the node,establishing a trusted foundation without relying on proprietary hardware.In a trusted execution environment,timed measurement code is executed to dynamically collect node measurements.Smart contracts are used to verify trust in three stages:initial,process,and final,with verified servers joining a trusted alliance chain,achieving trusted domain extension.Comparative analysis shows that this solution outperforms others in security,privacy,and flexibility.Security analysis and experiments confirm its high security and feasibility.关键词
