specific Embodiment approach

[0044] The present invention relates to a specific implementation of a quantum logic circuit construction method for multiplication in the field of encryption technology, including the following steps:

[0045] 1. First construct the basic circuit module: use the basic control NOT gate and exchange gate in the quantum logic circuit as the construction gate library of the basic module circuit, and the basic module structure:

[0046] The basic control NOT gate and exchange gate in the quantum logic circuit are used as the construction gate library of the basic circuit. Most of the operations in the encryption algorithm are based on the Galois field. Among them, addition and multiplication are the most common operations. The addition is the XOR of two numbers, which can be completed by using the quantum basic gate to control the NOT gate. The output of the target bit is the result of the mutual XOR of the data. Since it is based on GF(2 8 ), so the basic circuit uses 8 quantum w...

Embodiment 1

[0058] Embodiment 1: Let D min =14, 14 is carried out modulo 2 to get the remainder, and is transformed into 8 binary numbers, and the weight coefficient expansion formula corresponding to this binary number is given to get 14=2 3 +2 2 +2 1 , scan one at a time from the one with the smaller coefficient, D first max ×2 1 , add a U device, then the data at i is D max ×2 1 , continue to scan, detect the plus sign, add a control NOT gate for XOR operation, and the result at ii is still D max ×2 1 , the result at iii changed from 0 to D at this time max ×2 1 , continue to scan, and found 2 2 , add a U device again, according to this method, scan in turn until the highest coefficient item is scanned, the result at iV is D max ×2 2 , the result at V is D max ×2 2 +D max ×2 1 , the result at Vi is D max ×2 3 , and finally through a control NOT gate to complete the XOR operation of each part, the result at Vii is D max ×2 3 +D max ×2 2 +D max ×2 1 , the final res...

Abstract

The invention discloses a construction method of a quantum logic circuit for aiming at multiplication operation in an encryption technology field. The method comprises the following steps of constructing a base module, namely using a basic control Not gate and an exchange gate in the quantum logic circuit as a construction gate base of a basic circuit, and packaging the constructed basic circuit for forming a U device, thereby realizing add operation and multiplication operation; and constructing a high-grade circuit module. According to the construction method, a reversible logical design is utilized, and power consumption and behavior attribute of an electromagnetic field cannot be obtained through a traditional manner, thereby effectively preventing side channel attacks, and greatly reducing possibility of illegal crack. Better encryption effect of encryption technology is realized. Reversibility of the circuit can realize an encryption effect of 2n logic synthesis.

Description

technical field [0001] The invention belongs to the technical field of quantum information science. In particular, it relates to a method for constructing a quantum logic circuit for specific operations. Background technique [0002] The theft and secrecy of information is an eternal topic in the information society. How to design an encryption technology or algorithm with good encryption effect and low encryption cost has always been a research problem in the field of encryption technology. Through consulting the data, it is found that the current encryption technology, Most of them are based on mathematical problems, increasing the difficulty and time of deciphering by increasing the complexity of the encryption algorithm. And how to design an encryption algorithm with good encryption effect or less time required for encryption has become a common concern of everyone. [0003] A recent report by the Cloud Computing Security Alliance (CSA) summarizes nine "culprits" that ...
