Analysis and improvement of a chaos-based image encryption algorithm. (English) Zbl 1198.94132

Chaos Solitons Fractals 40, No. 5, 2191-2199 (2009).
Summary: The security of digital image attracts much attention recently. In Zh. Guan et al. [Phys. Lett., A 346, No. 1–3, 153–157 (2005; Zbl 1195.94056)], a chaos-based image encryption algorithm has been proposed. In this paper, the cause of potential flaws in the original algorithm is analyzed in detail, and then the corresponding enhancement measures are proposed. Both theoretical analysis and computer simulation indicate that the improved algorithm can overcome these flaws and maintain all the merits of the original one.
Editorial remark: There are doubts about a proper peer-reviewing procedure of this journal. The editor-in-chief has retired, but, according to a statement of the publisher, articles accepted under his guidance are published without additional control.
