Cryptanalysis is used to breach cryptographic security systems and gain access to the contents of encrypted messages, even if the cryptographic key is unknown.
How is cryptanalysis done?
Cryptanalysis is the study of methods for obtaining the meaning of encrypted information, without access to the secret information that is typically required to do so. Typically, this involves knowing how the system works and finding a secret key. Cryptanalysis is also referred to as codebreaking or cracking the code.
Which techniques can be used for cryptanalysis?
Cryptanalysis techniques for stream ciphers are:
- Exhaustive Key Search Attack.
- Side Channel Analysis Attack.
- Time Memory Trade off Attacks.
- Distinguishing Attacks.
- Algebraic Attack.
- Correlation attacks.
- Guess and Determine attacks.
- Linear Masking attacks.
