AbstractIn this paper, an adaptive scan chain structure based plaintext analysis technique is proposed. The technology is implemented by three circuits, including adaptive scan chain circuit, plaintext analysis circuit and controller circuit. The plaintext is analyzed whether meet the characteristics of the differential cryptanalysis in the plaintext analysis module. The adaptive scan chain contains MUX, XOR and traditional scan chain, which is easy to implement. If the last bit of two plaintexts differs by one, the adaptive scan chain is controlled to input them into different scan chain. Compared with complicated scan chain, the structure of adaptive scan chain is variable and can mislead attackers who use differential cryptanalysis attack. Through experimental analysis, it is proved that the security of the adaptive scan chain structure is greatly improved.
