摘要:

针对公有性验证模型中第三方审计机构(TPA,third-party auditor)不可信问题,提出基于TPA云联盟的数据完整性验证模型。首先,设计 TPA 云联盟的体系结构并定义系统平台的主要功能组件及作用,联盟可以对TPA云成员进行管理和控制。其次,利用可信计算技术和区块链技术对TPA进行详细的设计,确保TPA执行环境和工作流程的可信性。最后,利用TPA云联盟构建数据完整性验证模型,并对模型的正确性、安全性和有效性进行理论和实验分析。

关键词: 数据完整性验证, 区块链, 可信计算, 第三方审计机构

Abstract:

Aiming at the untrustworthiness of third-party auditor (TPA) in the publicity verification model,a data integrity verification model based on the cloud federation of TPA was proposed.Firstly,the cloud federation of TPA’s architecture was designed and the main functional components and function of the system platform was defined.The federation could manage and control the TPA cloud members.Secondly,TPA was designed in detail by using trusted computing technology and blockchain technology to ensure the credibility of the TPA execution environment and workflow.Finally,the data integrity verification model was built by using cloud federation of TPA.The correctness,security and effectiveness of the model were analyzed theoretically and experimentally.

Key words: data integrity verification, blockchain, trusted computing, third-party auditor
