A New Chaos-Based Color Image Encryption Scheme with an Efficient Substitution Keystream Generation Strategy
This paper suggests a new chaos-based color image cipher with an efficient substitution keystream generation strategy. The hyperchaotic Lü system and logistic map are employed to generate the permutation and substitution keystream sequences for image data scrambling and mixing. In the permutation st...
