effect. This paper studies the "extraordinary Key" and "to be trivial key" that are in the chaotic sequences that is caused by Logistic map, thus presents a image chaotic encryption algorithm that is based on hybrid chaotic sequence. Firstly, the algorithm generate hybrid chaotic sequence through the key; then through generates the corresponding offset matrix and permutation matrix the discrete mapping; finally, do the implementation of wavelet transform to the image, do the digital image scrambling

information encryption . Logistic mapping is one of the most typical types in chaotic systems. The content of this paper is mainly to use Logistic chaotic map to generate chaotic sequences to encrypt the data transmitted between readers and tags in RFID system, which guarantees RFID system security to some extent.

Introduction to chaotic mapping
The essence of chaotic encryption is serial cipher encryption. The basic principle is to divide the

chaotic sequence sampled from Colpitts oscillator can also be used to generate Toeplitz-structured chaotic sensing matrix. Simulation results show that the proposed Colpitts chaotic sensing matrix has similar performance to random matrix or other chaotic matrix for exact reconstructing compressible signals and images from fewer measurements.
