A verification method and system for cloud applications

Abstract

The invention provides a verification method and system for a cloud application. The method comprises the steps that when any two nodes interact, a receiving node pre-verifies a sending node needing to be verified, and when it is determined that the sending node passes the pre-verification, other nodes in a block chain network store integrity evidences of the sending node and integrity evidences of the receiving node into a block chain after voting is passed; the verification node determines a target node where a to-be-verified target cloud application is located and a to-be-verified target time period; and the integrity evidence of the target node is acquired in the target time period with the integrity evidence of the related node interacting with the target node in the target time period from the blockchain, and comparing the integrity evidence with pre-stored standard metric information to determine whether the target cloud application passes verification. According to the verification method and system for the cloud application, overhead of the verification process is reduced.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a verification method and system for cloud applications. Background technique [0002] In the existing technology, the certification of cloud applications needs to select a central delegator, and the central delegator is used to obtain the certification evidence generated by the TPM to verify other nodes in the cloud, and the central delegator completes the certification for each machine , and combine each individual corroborating result into the final corroborating evidence. [0003] The solution of the existing technology requires the user to rely on a central entruster to verify the internal cloud. In order to prove that a target cloud application is safe, the central entruster will verify all nodes in the entire cloud, and cannot separate the target The dependence on cloud applications has caused a lot of overhead. Contents of the invention [0004] Embodiments of the p...
