Research on double chaos encryption algorithm based on disturbance

In this paper, a chaotic model is designed and implemented based on Logistic map, then expansed control parameters, thus a double chaotic orbits are produced, they can against reconstruction of threats chaos. and disturbance of the method using Fibonacci sequence is mapped to an integer space, resolve the finite precision issue in the computer application, but also the length of the plaintext is introduced as control parameters, and enhance the randomness of chaotic sequence generated to further enhance the anti-crack, the protection of data is more safe.
