More Information
Summary:The invention provides backup and recovery methods and devices for data stored in a TEE, equipment and a medium, relates to the technical field of data processing, in particular to the technical field of trusted computing and block chains, and can be used for cloud computing. The specific implementation scheme is as follows: acquiring a backup request; wherein the backup request comprises identification information of a backup trusted program in a backup machine; generating data to be transmitted according to the original ciphertext of the sealed data in the local trusted execution environment; and according to the identification information of the backup trusted program, sending the to-be-transmitted data to the backup trusted program, so that the backup trusted program determines a sealed data plaintext according to the to-be-transmitted data, and associates, encrypts and backs up the sealed data plaintext and the business trusted program in a local TEE. According to the technology disclosed by the inventio
