Abstract

The invention discloses a cloud service auditing system and method based on a blockchain, and the system comprises a user side which monitors the attribute quality of a cloud service, carries out OREencryption on a monitoring result, and then uploads the monitoring result to the blockchain; a cloud service provider side which performs real-time cloud service attribute quality monitoring by a TPMmodule, performs ORE encryption on a monitoring result and then uploads the monitoring result to the blockchain; an auditing contract module which audits the cloud service attribute quality detectionresults of the user side and the cloud service provider side, verifies the authenticity of the monitoring results, determines whether the cloud service quality reaches a standard or not, carries out cloud service provider reward distribution or violation compensation according to an auditing result, and updates the reputation value of the cloud service provider; and a blockchain storage module which is used for storing the cloud service attribute quality data monitored by the user and the cloud service provider, and storing an audit contract execution result and a reputation value of the cloudservice provider. The system solves the problems of untrusted auditing result and user privacy leakage in the existing cloud service auditing system.

Description

technical field [0001] The invention belongs to the field of cloud service security, specifically a review method for cloud service quality, and designs and proposes a blockchain-based cloud service review system and review method. Background technique [0002] In recent years, cloud computing technology has developed rapidly, and cloud service has become one of the popular service models. Cloud service providers can provide users with scalable, on-demand cloud services that save user time and other resources. However, while this cloud service model provides convenient services for users, there are also problems with the quality of services provided by cloud service providers. Therefore, the cloud service level agreement (SLA) came into being. A cloud SLA is an agreement between a user and a service provider that specifies the quality requirements for each service. When the performance of the provided cloud service fails to meet the SLA requirements, that is, when an SLA ...
