  • Method for generating public key and secret key based on module-wavy and module-LWR and method of encryption and decryption using the keys
    Patent number: 11658819
    Abstract: The computer-implemented method for generating a public key and a secret key of the present disclosure comprises determining, by a processor, the secret key (s) by sampling from a distribution over {?1, 0, 1}nd; determining, by a processor, a first error vector (e) by sampling from (D?qn)d and a second error value (e?) by sampling from D?qn; choosing, by a processor, a randomly uniform matrix A which satisfies A·s=e (mod q); choosing, by a processor, a random column vector b which satisfies ? b , s ? = ? q 2 ? + e ? ? ( mod ? ? q ) ; and determining, by a processor, the public key (pk) by (A?b)?Rqd×(d+1).
