摘要
For the realization of chaos encryption in higher dimension and improving security, in this paper, a new four-dimensional hyperchaotic finance system based on a chaotic finance system is presented. The chaotic sequence is generated by using Runge-Kutta method, the key sequence is generated by chaotic sequence comparison. The key sequence is used for image encryption with relation to plaintext. The results of several analyses about histogram, randomness and information entropy of the encrypted image show that the new hyperchaotic system has high security and complexity.
