Abstract
Image encryption based on chaotic sequence is an important hot research issue in the field of application at present. The quality of chaotic sequence, such as ergodicity, initial value sensitivity, dense periodicity and so on, is of great significance. In view of the good chaotic characteristics of trigonometric function system, this paper constructs a system of summation after product of two sinusoidal functions, and a system in which a linear function term is added after the product of trigonometric functions. The experimental analysis proves that the system has strong chaotic characteristics. Some equivalent forms of the system are discussed, and the chaotic sequences of the system are used for image encryption, and good encryption effect is achieved.
