Chaos based crossover and mutation for securing DICOM image

“…The combined chaotic system tends to overcome the disadvantages of 1D and higher order chaotic maps [37][38][39][40][41][42][43][44][45]. In [44], three 1D combined chaotic maps are proposed to achieve the tradeoff between computational cost and security.…”

An Efficient Radical Image Encryption Based on 3-D Lorenz Chaotic System

“…The key space should be large enough to resist the attacks such as brute force attack as much as possible. Here we determine the initial conditions and canonical parameters x 0 , y 0, z 0, , , , SK 1 , SK 2 and SK 3 as keys. The computational precision of the floating point number is about 10 14 , so the key space can grow up to 10 126 this is large enough to beat out the attacks.…”

Digital Image Encryption using Logistic Chaotic Key-based RC6

“…Considering the fact that a good cipher should generate cipher-images that cannot be discerned from true random images in order to prevent entropy attacks and reduce the information leakage [32]. Therefore, entropy of encryptedimages should approach the maximum possible value.…”

“…Differential cryptanalysis aims to reveal some insightful relationships between the encrypted and plain images by figuring out the effects of a tiny change (e.g., just a single pixel) in plain-images on their corresponding cipher-images [32]. Hence one of the vital assessment for a cipher is to measure to what extent a minor change in plain-image can yield a completely different ciphered images.…”
