  • Method for preventing differential cryptanalysis attack
    Patent number: 11520934
    Abstract: A method for preventing a differential cryptanalysis attack is provided. The method is implemented by an adaptive scan chain, a control module, and a plaintext analysis module. The plaintext analysis module controls the adaptive scan chain, so that two plaintexts differing in the last bit of only one byte are input through scan chains with different structures. Consequently, the two input plaintexts for which differential cryptanalysis attack technology originally can be used to crack the key are unable to generate outputs that can be used by the differential cryptanalysis attack technology.
    Type: Grant
    Filed: March 12, 2021
    Date of Patent: December 6, 2022
    Assignees: Nanjing University Of Posts And Telecommunications, NANTONG INSTITUTE OF NANJING UNIVERSITY OF POSTS AND TELECOMMUNICATIONS CO., LTD.
