linear cryptanalysis

Linear cryptanalysis is a method used to analyze and break cryptographic algorithms by finding approximate linear relationships between a cryptographic key and the data they encrypt. Attackers examine many encrypted messages and look for patterns or correlations that consistently appear, which can reveal parts of the secret key. Essentially, it exploits predictable patterns in the encryption process, allowing a attacker to gradually uncover the key with enough data, making the cipher less secure. It’s a statistical approach that leverages mathematical relationships to test the strength of encryption methods.
