Popis: In this chapter, a modified Tinkerbell chaotic generator based substitution method is proposed for an image encryption algorithm. The correlation between the adjacent elements in the sequence generated by modified Tinkerbell generator is very less and gives high degree of randomness. This sequence is introduced in the substitution stage of encryption process to diffuse the pixel value of cipher image after transformation. The cipher images are subjected to various security analysis and the results obtained are compared with many existing techniques to prove high degree of security.
