Data storage method based on identity in cloud computing and integrity verification method based on identity in cloud computing

Abstract

The invention discloses a data storage method based on an identity in cloud computing and an integrity verification method based on the identity in cloud computing, and belongs to the technical field of network security. The data storage method comprises the steps that a cloud user generates a secret key application request carrying a public key generated based on the ID of the cloud user, and sends the secret key application request to a KGC server, and a corresponding private key is generated by the KGC server and sent back to the cloud user through a secure channel; the cloud user conducts block division on files to be uploaded, and generates data block labels of data blocks on the basis of the private key, corresponding file labels are generated by the data block labels, and the file labels and the files are uploaded to a cloud server. When the integrity of the files on the cloud server needs to be verified, integrity verification based on the identity is achieved based on zero-knowledge proof between a verification server and the cloud server. The data storage method based on the identity in cloud computing and the integrity verification method based on the identity in cloud computing are used for cloud storage and integrity verification of storage. When the data storage method and the integrity verification method are applied, management of certificates can be remarkably simplified, and the system complexity is reduced; meanwhile, when integrity verification is conducted, the effectiveness of the public key of the cloud user does not need to be verified, and the system complexity is simplified.
