Embodiment Construction

[0034] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0035] The described chaotic fractional-order encryption circuit includes a data encryption function module built with a fifth-order fractional-order chaotic memory group circuit as the core, and the design method of the described fifth-order fractional-order chaotic memory group circuit is as follows:

[0036] (1) if figure 1 As shown, referring to the nonlinear circuit of two fractional order memristors, the corresponding differential equation is obtained:

[0037]

[0038] (2) Define nonlinear functions q(ξ) and W(ξ) respectively, and let

[0039] x=φ 1 ,y=φ 2 ,z=v 3 ,u=v 4 ,v=i 5 , d=G,e=R,C 2 = 1

[0040] q(ξ)=ξ+ξ 3

[0041]

[0042] Then the above equation of state can be written as:

[0043]

[0044] W in the above formula 1 =1+3x 2 , W 2 =1+3y 2 ;

[0045] (3) Discretize the above formula to get: In the for...

Abstract

The invention discloses a chaotic fractional order encryption circuit. According to the invention, a data encryption energy supply module is built by taking a five-order fractional order chaotic memory group circuit as a core, and a five-order continuous differential equation is discretized into a five-order differential equation through a discretization method, so that a computer can carry out iterative operation more conveniently; and meanwhile, encryption circuit design is carried out based on the five-order fractional order chaotic circuit, so that the encryption circuit can be more suitable for an encryption communication module for communication between small-scale electronic equipment, and real-time and high-reliability encryption is carried out on transmission signals.

Description

technical field [0001] The invention relates to a transmission signal encryption circuit, in particular to a chaotic fractional order encryption circuit. Background technique [0002] At present, chaotic information technology has been widely used in the fields of computer network, circuit system and laser system. With the combination of various directions of chaotic technology, the encryption requirements for information transmission are becoming more and more stringent. [0003] Although there are already many circuit designs based on chaotic modules in the industry, no one has done relevant design for the use of fractional chaotic encryption, and many encryption modules are not satisfactory in terms of encryption efficiency, often time-consuming. Long, and many encryption modules that take a short time cannot perform more complex encryption, and their practical performance is not strong.
