Outage storage type SIMON encryption circuit

Abstract

The invention discloses an outage storage type SIMON encryption circuit comprising two n-digit shifting registers, two n-digit serial-to-parallel circuits and an n-digit ciphertext generation circuitbased on memristors. Each digit of ciphertext generation circuit based on the memristors comprises a column mixing module, a first waveform adjustment module, a round key encryption module and a second waveform adjustment module, wherein the column mixing module comprises a first two-input AND gate that comprises a first memristor and a second memristor; the first waveform adjustment module comprises a first phase inverter and a second phase inverter; the round key encryption module comprises three two-input XOR gates having the same structure; each two-input XOR gate comprises a third phase inverter, a fourth phase inverter, a two-input OR gate, a second two-input AND gate and a third two-input AND gate; the two-input OR gate comprises a third memristor and a fourth memristor; and the second waveform adjustment module comprises a fifth phase inverter and a sixth phase inverter. The circuit provided by the invention has the advantages that when in outage, the data can be automaticallystored, and the data loss is avoided.

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...

AI Technical Summary

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
