WebNov 4, 2024 · Confusion and diffusion are two important cryptographic properties [ 1 ]. The confusion is responsible for making the relation between key and ciphertext as complex as possible, and the diffusion is to spread the internal dependencies as much as possible. Both concepts are very important for the overall security and efficiency of the ciphers.
