New Chaotic Substation and Permutation Method for Image Encryption is introduced based on combination betweenBlock Cipher and chaotic map.The new algorithm encrypts and decrypts a block of 500 byte.Each block is firstly permuted by using the hyper-chaotic map and then the result is substituted using 1D Bernoulli map.Finally the resulted block is XORed with the key block.The proposed cipher image subjected to number of tests which are the security analysis (key space analysis and key sensitivity analysis) and statistical attack analysis (histogram, correlation, and differential attack and information entropy) and all results show that the proposed encryption scheme is secure because of its large key space; it's highly sensitivity to the cipher keys and plain-images.
