Cryptography confusion and diffusion

WebMar 16, 2024 · Basically, these properties help in designing a cryptographic algorithm that can avoid the threat of cryptanalysis. Some ciphers employ just confusion techniques in their constriction, while others use both confusion and diffusion techniques, making them more secure. 3. Categorization of Cryptographic Ciphers WebThe simplest way to achieve both diffusion and confusion is a substitution-permutation network. In these systems, the plaintext and the key often have a very similar role in …
