  • Publication number: 20240113809
    Abstract: The present application provides an instruction encoding-based data processing method and apparatus, and a device. N-path error correction encoding is performed on an instruction in information to be processed to obtain N encoded instructions, the encoded instructions and encoded meta channel programs obtained by the error correction encoding are used to perform redundant processing on data to be processed to obtain N pieces of response data, and then error correction decoding is performed on the N pieces of response data to obtain processing result information of the information to be processed. Because the N encoded instructions are heterogeneous and the encoded meta channel programs used in the N-path processing are heterogeneous, the randomness of the processing process can be improved, generalized disturbance in the data processing process can be corrected in combination with the error correction encoding and decoding methods, and thus the security of data processing is improved.
