[0004] The literature [1] of Chen Jiaqing, Guan Zhijin, Cheng Xueyun, etc. is based on the design and hardware implementation of quantum reversible logic encryption algorithm [J]. Journal of PLA University of Science and Technology (Natural Science Edition), 2018, 0(0): 1-3. Main It describes the effectiveness and feasibility of the AES algorithm based on the quantum reversible circuit to realize the 128-bit secret key by introducing the quantum circuit and electronic circuit implementation method of column mixing and round key addition. However, this document only introduces the AES algorithm based on the quantum reversible circuit. The hardware implementation of the encryption and decryption algorithm has not completed the setting of the encryption system, and lacks the quantum reversible circuit key expansion module and the corresponding interface module, which will greatly reduce the encryption effect and complexity of the encryption system, resulting in its lack of practicability and cannot be invested. use
