Problems solved by technology
[0004] Although there have been researches on data recovery, most of the existing schemes are still at the stage of integrity verification, and there is no actual recovery method; or simply use erasure codes to encode the original file, but this recovery rate is low
[0005] In addition, in some of the few schemes based on encoding to realize data recovery, the calculation overhead of the scheme is extremely large, which increases the overhead burden of the entire system

Abstract
The invention discloses a cloud side data integrity verification and restoration method based on IDA. The method comprises the following steps of 1, user initialization; 2, storage block generation; 3, vector quantity encryption; 4, label generation; 5, challenging auditing; 6, challenging responding; 7, responding verification; 8, original data restoration. According to the scheme, an original file is encoded, and damaged data is completely restored on the basis of verifying cloud side data integrity. Meanwhile, under the condition of guaranteeing system safety, the complexity of completely verifying labels and restoring calculation is reduced, and the efficiency of the method is effectively improved.
Description
technical field [0001] The invention relates to the fields of cloud storage and information security, in particular to an IDA-based cloud data integrity verification and recovery method. Background technique [0002] With the widespread application of cloud storage services, more and more users store data in the cloud. However, the cloud server is "semi-trusted". After the user stores the data in the cloud, he will lose control of the data, so it is impossible to determine whether the data in the cloud server is complete. When the data is destroyed, it is impossible to restore the corresponding original data. data. Therefore, how to recover the original data of the damaged data while verifying the integrity of the data has become an urgent problem to be solved. [0003] Aiming at the problem of integrity verification, researchers have proposed many auditing schemes for integrity verification in cloud storage. These schemes use signatures, tags and other means to verify th...
