摘要：The need and importance of secure information communication, particularly text, image and video transmission has made cryptography to take a larger space in current research era. Improvement of pictorial information for betterment of human perception involves de-blurring, de-noising and safe transmission. These applications extend over several fields such as satellite imaging, medical imaging etc. Specifically we would like to elaborate our research on the significance of computational intelligence as one of the domains which finds application in cryptography and information security, and then the relevance of cryptography is indeed unavoidable. This paper deals with the study of the requirements for strong cryptography and various computational intelligence techniques that find use in cryptography. Cryptanalysis is a well-studied problem with many important applications in the areas of error-free and secure data transmission. In this paper, we have reviewed the improved algorithms used for cryptography optimization; the algorithms under reviews integrate genetic algorithms, immune computing, crossover and mutation operators and fuzzy systems to maintain the diversity and optimization of candidate objects. These computational intelligence techniques have seen to greatly improve the fitness levels of candidate groups in cryptography. Lastly, we make detailed comparison between these methods and those cryptography techniques without computational intelligence.
