A structural encoding unit and an error correction decoding unit are divided. The structure encoding unit is divided into input branch processor and an input proxy processor; and the error correction decoding unit is divided into an output routing processor, an output proxy processor, an adjudication branch processor, an adjudication proxy processor and a voting processor. The input branch processor is used for duplicating and distributing messages, the arbitration branch processor is used for duplicating and distributing data, the voting processor is used for performing voting, and the output routing processor is used for selecting an output result from processing results of the output proxy processor according to a voting result of the voting processor.

Input/output system applied to network security defense system

Provided are a data processing system and method based on dynamic redundancy heterogeneous encoding, and a device. The method comprises: respectively performing error correction encoding on information to be processed and a processing rule, so as to form encoded information to be processed and an encoded processing rule; processing, by using the encoded processing rule, the encoded information to be processed, so as to obtain response data; and then performing error correction decoding on N pieces of response data, so as to obtain processing result information of the information to be processed.

Data processing system and method based on dynamic redundancy heterogeneous encoding, and device

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.

Instruction encoding-based data processing method and apparatus, and device
