Description

Technical field [0001] The present invention relates to the field of information security techniques, and more particularly to a processor for implementing a post-quantum password SABER algorithm. Background technique [0002] In the information security technology, in order to ensure the security of the information, the transmitting end needs to be encrypted before the information transmission is required. After receiving the information, the information is required to decrypt the information using the corresponding key. [0003] With the development of technology, password technology is developing from the traditional public key-based password technology to PQC (Post-Quantum Cryptography, the post-quantum password) technology direction. The so-called PQC technology refers to a password technology that can resist quantum computer attacks. Reference to "anti-quantum cryptography". The "post" refers to the existing public key cryptographic algorithm (such as RSA, Diffie-Hellman, e...
