A New Chaos-Based Color Image Encryption Scheme with an Efficient Substitution Keystream Generation Strategy

<div>Histogram analysis. (a) and (h) are the test image and its output cipher-image, respectively. (b)–(d) and (i)–(k) are the three color channels of (a) and (h), respectively. (e)–(g) and (l)–(n) are the histograms of (b)–(d) and (i)–(k), respectively.</div>
