Data encryption method and system based on quantum computing resistance

Abstract

The invention relates to the technical field of data security, and discloses a data encryption method and system based on anti-quantum computing, and the method comprises the steps: obtaining character data, letter data and image data, carrying out the homologous encryption of a first elliptic curve according to the character data, obtaining a character encryption feature, and carrying out the homologous encryption of a second elliptic curve according to the letter data, carrying out second elliptic curve homologous encryption to obtain letter encryption features according to the image data, carrying out third elliptic curve homologous encryption to obtain image encryption features according to the image data, carrying out data integration according to the text encryption features, the letter encryption features and the image encryption features to obtain an encrypted data set, carrying out first encryption according to the encrypted data set, and carrying out second encryption according to the encrypted data set. And performing first encryption according to the first encryption element to obtain a first encryption element, performing second encryption according to the first encryption element to obtain a second encryption element, and sending the second encryption element to a data receiver. According to the method, the security of the encrypted data and the capability of resisting the quantum computing attack can be improved.
