Organizations responsible for data security cannot afford to wait for quantum to arrive before building their defenses.

In this paper, a color image encryption scheme based on 4D hyperchaos system and RSA algorithm is proposed. Firstly, RSA algorithm is used to generate the initial value of 4D hyperchaotic system, and ...

The Internet is developing rapidly, which leads to a sharp increase in information transmitted by the network. Moreover, people have a higher demand for encrypting meetings and encrypting information ...
