A packet encryption algorithm based on chaotic mapping
Wang Baoping · 2013
In order to improve the security of image encryption,a new image encryption method combined with the chaotic map and the triangular chaotic map is proposed.Firstly,the triangular chaotic sequence generated by the triangular chaotic map is quantified into discrete binary sequence.Secondly,the random properties of binary sequence are analyzed.In the end,the triangular chaotic map is applied to the improved encryption algorithm based on quasi-feistel structure.The encrypted image is analyzed with gray level co-occurrence matrix(GLCM).The results show that the neighborhood pixels of encrypted image have good performance of space random uniform distribution.
