Web8 Dec 2024 · The SPN takes each block and combines it with the 48-bit secret key, producing 16-bit ciphertext blocks as output. A SPN takes a block of the plaintext and the key as inputs, and applies several alternating rounds of substitution boxes (S-boxes) and permutations to produce a ciphertext block.
