Abstract
A secure processor for a post-quantum cryptography (PQC) algorithm CRYSTALS-KYBER, includes a communication unit, a management unit, a processing unit, and a storage unit. The communication unit is configured to receive and transmit data for the secure processor; the management unit is configured to control the processing unit according to the data; the processing unit is configured to process the data to form encrypted data, decrypted data and key data; and the storage unit is configured to store all data. The secure processor can efficiently and rapidly realize key generation, encryption and decryption of a KYBER algorithm under KYBER1024, KYBER768 and KYBER512 security levels, makes data encryption more complicated, and ensures security of the data.
