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.
