  • Apparatus and method for encryption
    Patent number: 10491374
    Abstract: Disclosed are an apparatus and a method for encryption. The apparatus includes a key table generator configured to generate random values based on a seed value and generate a key table including the generated random values; and an encryptor configured to apply the generated key table to a round function, generate a block encryption algorithm having a Feistel structure based on the round function, and encrypt a plaintext data block based on the generated block encryption algorithm.
    Type: Grant
    Filed: December 28, 2015
    Date of Patent: November 26, 2019
    Assignees: SAMSUNG SDS CO., LTD., CARMEL HAIFA UNIVERSITY ECONOMIC CORP. LTD., BAR-ILAN UNIVERSITY
    Inventors: Duk-Jae Moon, Ji-Hoon Cho, Kyu-Young Choi, Nathan Keller, Orr Dunkelman, Itai Dinur
  • Apparatus and method for encryption
    Patent number: 10411880
    Abstract: Disclosed are an apparatus and a method for encryption. The apparatus includes, a key table generation unit configured to generate random values derived from a seed value and generate a key table including the generated random values, and an encryption unit configured to encrypt a plain text data block by generating an encryption algorithm by repeatedly combining the generated key table with a permutation function in a crossing manner, and using the generated encryption algorithm.
