Various Techniques of Cryptanalysis, Their Challenges and Remedial Solutions

Cryptanalysis is a technique that extract the text or information from encrypted text. Nowadays, breaking or hacking the cryptographic algorithm is called as cryptanalysis. It is an approach to find the flaws or weakness within a cipher to make them stronger. This paper provides a comprehensive overview of various techniques of cryptanalysis used for stream ciphers, the challenges encounter in their implementation and potential solutions to address these challenges. This paper covers total nine cryptanalysis techniques which are used to extract information from stream ciphers.
