[0108] The first embodiment of the present invention provides an encoding system for preventing quantum attacks. The system includes an encoding end and a decoding end. The embodiment of the present invention does not impose any restrictions on the encoding end and the decoding end. The encoding end and the decoding end can be For arbitrary terminals such as computers and servers, the encoding end implements a quantum attack-proof encoding method. The decoding end implements a quantum attack-proof decoding method, and the decoding method is the inverse process of the encoding method. For ease of understanding, before introducing the method, the round function of the nonlinear weighting coefficient used in the method is introduced.

[0109] First, the round function of the nonlinear weighting coefficient;

Abstract

The invention provides an encoding method, device, medium and electronic equipment for preventing quantum attacks, and relates to the technical field of communication encoding. The method includes randomly generating a binary two-dimensional table, searching for a first bit value corresponding to the i-th symbol in the first binary sequence from the binary two-dimensional table based on lattice theory; A second bit value corresponding to the i-th symbol in a binary sequence, constructing a nonlinear round function based on the second bit value; constructing a weighted probability model, and encoding the first binary sequence according to the coding formula according to the weighted probability model, A first encoding result is obtained; a second encoding result is obtained based on the first bit value and the first encoding result. The quantum-attack-resistant encoding device is applied to a quantum-attack-resistant encoding method. The encoding method for preventing quantum attacks is applied in electronic equipment.

Description

technical field [0001] The present invention relates to the technical field of communication coding, and more particularly, to a coding method, device, medium and electronic equipment for preventing quantum attacks. Background technique [0002] Lossless compression algorithms (entropy coding) have been widely used in communication, storage and other technical fields. Common lossless compression algorithms include run-length coding, dictionary coding, Huffman coding, and arithmetic coding (interval coding). As the core tool of information security, symmetric encryption algorithm is also widely used in the fields of communication, transaction, payment and data desensitization. Common symmetric encryption algorithms include Data Encryption Standard (DES), Advanced Encryption Standard (Advanced Encryption Standard) , AES), a symmetric encryption block algorithm (Blowfish), etc. [0003] However, the current existing symmetric encryption is a linear encoding process and cannot ...
