  • Patent number: 11569980
    Abstract: Hardware circuitry defines logic for both Sbox generation and inverse Sbox generation via generating a multiplicative inverse matrix as a truth table for data. The hardware circuitry receives input plain text to be encrypted. The hardware circuitry divides the input plain text to be encrypted. The hardware circuitry feeds multiplicative inverse values generated from the input plain text to a transformer module for performing affine to encrypt the plain text data. The hardware circuitry receives encrypted data to be decrypted. The hardware circuitry divides the encrypted data to be decrypted. The hardware circuitry feeds multiplicative inverse generated from the encrypted data to the transformer module for performing inverse affine to decrypt the encrypted data.
