Cryptographic diffusion
In cryptography, confusion and diffusion are two properties of the operation of a secure cipher identified by Claude Shannon in his 1945 classified report A Mathematical Theory of Cryptography . These properties, when present, work to thwart the application of statistics and other methods of … See more Confusion Confusion means that each binary digit (bit) of the ciphertext should depend on several parts of the key, obscuring the connections between the two. The property of … See more • Algorithmic information theory • Avalanche effect • Substitution–permutation network See more In Shannon's original definitions, confusion refers to making the relationship between the ciphertext and the symmetric key as complex and … See more Designing an encryption method uses both of the principles of confusion and diffusion. Confusion means that the process drastically changes data from the input to the output, for example, by translating the data through a non-linear table created from … See more WebThe basics of cryptography are valuable fundamentals for building a secure network.

WebNov 12, 2024 · Cryptography is commonly used to secure communication and data transmission over insecure networks through the use of cryptosystems. A cryptosystem is a set of cryptographic algorithms offering security facilities for maintaining more cover-ups. A substitution-box (S-box) is the lone component in a cryptosystem that gives rise to a … WebThe statistical tests are used to explore the cryptographic properties such as diffusion, confusion, independence, and randomness in the subkeys generated by the key schedule algorithm. The proposed criterion has been applied to some of the key schedule algorithms of different block ciphers.
WebIn cryptography, an SP-network, or substitution–permutation network ( SPN ), is a series of linked mathematical operations used in block cipher algorithms such as AES (Rijndael), 3-Way, Kalyna, Kuznyechik, PRESENT, SAFER, SHARK, and Square . WebJul 5, 2024 · It corresponds to the concepts of key design, confusion, diffusion, and round-robin in cryptography, which makes chaos theory have great potential in the field of cryptography. In the last decades, many methods of image cryptography are introduced based on chaos theory [12,13,14,15,16,17,18,19,20]. Because of the limitation of computer ...
