Cryptographic diffusion

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.

WebThe bit confusion, bit diffusion, independence, and randomness are desirable cryptographic properties of subkeys generated by any KSA. Therefore, it is proposed that a KSA may at least be tested against these properties. This research work aims to propose testing criteria to evaluate the cryptographic strength of any key schedule algorithm.
