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. WebNov 18, 2024 · The DES (Data Encryption Standard) algorithm is a symmetric-key block cipher created in the early 1970s by an IBM team and adopted by the National Institute of Standards and Technology (NIST). The algorithm takes the plain text in 64-bit blocks and converts them into ciphertext using 48-bit keys. 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 . curly woman mx
