Emerging communication technologies in distributed network systems require transfer of biometric digital images with high security. Network security is identified by the changes in system behavior which is either Dynamic or Deterministic. Performance computation is complex in dynamic system where cryptographic techniques are not highly suitable. Chaotic theory solves complex problems of nonlinear...
A novel image encryption algorithm based on a hybrid model of deoxyribonucleic acid (DNA), cellular automata (CA) and chaotic system is proposed. CA due to its complex behavior has several applications such as generating random numbers and cryptography. DNA rules, DNA sequence XOR operator and CA rules are used simultaneously to encrypt the plain-image pixels. To determine rule number in DNA sequence...
An efficient image encryption algorithm with improved image security has been developed by using chaotic function, deoxyribonucleic acid (DNA) sequencing and genetic algorithm (GA). A chaotic sequence of desired length is generated by using the logistic map function whose initial value is calculated using the secret key. A number of DNA masks are generated and these masks along with the chaotic sequences...
