Abstract
The present disclosure relates to a data processing method, apparatus and computer readable storage medium, and relates to the technical fields of data storage and computer. The method of the present disclosure includes: sending a digest of data to be stored to a trusted execution environment; receiving combined information and a signature thereof returned by the trusted execution environment, wherein the combined information comprises the digest of the data to be stored, a timestamp and a monotonic counter value which are generated by the trusted execution environment and correspond to the data to be stored; and storing the data to be stored, the combined information and the signature.
Claims20
A data processing method, comprising:
- sending a digest of data to be stored to a trusted execution environment;
- receiving combined information and a signature thereof returned by the trusted execution environment, wherein the combined information comprises the digest of the data to be stored, a timestamp and a monotonic counter value which are generated by the trusted execution environment and correspond to the data to be stored;
- and
- storing the data to be stored, the combined information and the signature.
A data processing apparatus comprising:
- a processor;
- and
- a memory coupled to the processor, configured to store instructions which, when executed by the processor, cause the processor to:
- send a digest of data to be stored to a trusted execution environment;
- receive combined information and a signature thereof returned by the trusted execution environment, wherein the combined information comprises the digest of the data to be stored, a timestamp and a monotonic counter value which are generated by the trusted execution environment and correspond to the data to be stored;
- and
- store the data to be stored, the combined information and the signature.
A non-transitory computer-readable storage medium having a computer program stored thereon, wherein the program when executed by a processor, cause the processer to:
- send a digest of data to be stored to a trusted execution environment;
- receive combined information and a signature thereof returned by the trusted execution environment, wherein the combined information comprises the digest of the data to be stored, a timestamp and a monotonic counter value which are generated by the trusted execution environment and correspond to the data to be stored;
- and
- store the data to be stored, the combined information and the signature.
