Digital image encryption algorithm based on tent chaotic sequence
Zhai Yi-y · Modern Electronics Technique · 2014
Tent chaotic mapping structure is simple,but has good chaotic sequence random performance,which can be detected by NIST(National Institute of Standards and Technology). When chaos is applied to the digital image encryption,the initial value and the control parameters of the chaotic systems are always given. The improved chaotic sequence is used in this paper to connect the generation of the initial value with the plaintext image. The random sequences generated by Tent mapping are employed in scrambling the image and changing the pixels of the image. The simulation results show that the algorithm is valid and has perfect safety performance for the encryption and decryption.
