Методи криптоаналізу cучасних шифрів

Abstract

Nowadays, information plays a key role. Ciphers are used for information protection. Cryptanalysis deals with the discovery of the output text or key that will allow the ciphertext to be decrypted. It plays a very significant role in information security, as it is used both by cipher developers and by hackers who want to gain access to protected data. In order to understand how secure a particular cipher is, you need to analyze it and find bottlenecks in its mathematical base. Cryptanalysis is very important because it studies the security of a cipher and its key, and the key denotes the strength of the entire cryptosystem.
