Research of security risks in image encryption based on Logistic mapping
Xiu Zhang · Microcomputer & its Applications · 2010
The random features of the sequence generated by Logistic mapping are analyzed and the security risks are then found when a Logistic sequence is used for image encryption. Logistic sequence is not always chaotic even if the parameter μ∈(3.569 9 …,4] of Logistic mapping,there still exist a few periodic windows. Some rules are proposed in this paper for avoiding the security risks when Logistic mapping is used for image encryption.
