Description

technical field [0001] The invention relates to a SIMON encryption circuit, in particular to a power-off storage type SIMON encryption circuit. Background technique [0002] SIMON was proposed by the National Security Agency (NSA) of the United States in 2013. It belongs to a series of highly optimized block ciphers and can provide excellent performance in a hardware environment. The traditional SIMON encryption circuit adopts CMOS design technology, mainly including shift register, serial-to-parallel circuit, column mixing module and round encryption module. When the traditional SIMON encryption circuit is working, the plaintext is sequentially input into the shift register for shifting, and then converted into parallel data through the serial-to-parallel circuit, and the parallel data is sequentially processed and rounded by the column mixing module. The encryption module obtains the ciphertext after performing the round encryption operation. In the traditional SIMON enc...

Problems solved by technology

In the traditional SIMON encryption circuit, the shift register, serial-to-parallel circuit, column mixing module and round encryption module are all designed based on MOS tubes, and the MOS tube itself is not non-volatile. Therefore, the SIMON encryption circuit is running If there is a sudden power failure during the process, the data in it will not be saved, and some important data will be lost
