Abstract

The invention discloses a multi-scroll chaotic signal generator and an encryption system. The chaotic signal generator comprises an x signal output end, a y signal output end, a z signal output end, an F connection end, a basic chaotic signal generation circuit N1, and a function generation circuit N2. The encryption system performs encryption through the chaotic signal generator. The chaotic signal generator can generate complex chaotic signals, improve signal dimension and improve complexity of the chaotic signals. The encryption system is larger in secret key space and stronger in anti-decoding capability. The method is mainly applied to the technical field of chaotic encryption.

Description

technical field [0001] The invention relates to the technical field of chaotic encryption, in particular to a multi-scroll chaotic signal generator and an encryption system. Background technique [0002] Since Lorenz discovered the first chaotic system in the 1960s, the chaotic system has been widely used in image encryption, information security and other fields because of its strong sensitivity and dependence on initial conditions and parameters, and unpredictability. s concern. As a deterministic random-like process in nonlinear dynamical systems, chaos has ergodic, mixed and exponential divergence. The chaotic signal output by the existing chaotic signal generator has low dimension and low complexity. Therefore, the encryption system obtained by using the chaotic signal generator also has the problem of being easy to crack. Contents of the invention [0003] The purpose of the present invention is to provide a multi-scroll chaotic signal generator and encryption sys...
