“…If the value in right (or down, lower -right) corner does not exist within CML block, other values should be selected in left (or top, upper left) corner to replace. Based on these pixels, the values are calculated by following rules to fill in the substitution table T. Just take the pixel for example, the pixel is selected from CML block, and then we will finish the first column in substitution Table T Step 4 Use another logistic map to get a sequence M , modify its value range within [1,4] by formula (6). Especially, we get the initial value x0 for logistic map by Formula (5).…”

“…Most methods have been proposed on the chaotic image encryption [2][3][4][5][6][7][8][9], but many have proved the weak security for some chaotic encryption schemes [10][11][12][13]. Most common problems among unsecured encryption schemes are the chaotic dynamics degradation.…”

“…The permutation is achieved by scrambling all the pixels as a whole using 2D chaotic map (such as Baker map, Arnold cat map etc.) [3,4,10,12]. During diffusion, the pixel values are modified sequentially and the change made to a particular pixel depends on the accumulated effect of all the previous pixel values.…”

Advanced image encryption schemes for secure transmission and storage are increasingly needed for a number of applications like medical, military, satellite etc. In this paper, a novel image encryption algorithm based on Logistic and Tinkerbell map is proposed.The proposed method uses two 1-D Logistic maps with different keys and one 2-D Tinkerbell map. The chaotic sequence generated is mixed sequence from the and sequences of Tinkerbell map depending on the chaotic sequences of two logistic maps. The main advantage of such a scheme is complex chaotic behavior of the generated chaotic sequences. The security and performance of the proposed method is analyzed thoroughly by using key-sensitivity, keyspace, statistical, entropy, differential and performance analysis. The proposed approach achieves the required level of security with only one round of encryption operation. Hence the proposed method is computationally efficient.

“…The substitution process is initialized with the initial vectors generated via the cipher keys and chaotic standard map, and then the pixel gray values of row and column pixels of input 2D matrix are bitwise exclusive OR with the pseudo-random number sequences. Zhou et al introduced new chaotic systems by integrating the tent, Logistic and sine maps into one single system to produce the pseudo-random sequence [18,19]. The intertwining Logistic map and reversible cellular automata were applied in an image encryption scheme presented by Wang et al in [20].…”
