WebThe initial and final permutations are shown as follows − Round Function The heart of this cipher is the DES function, f. The DES function applies a 48-bit key to the rightmost 32 bits to produce a 32-bit output. Expansion Permutation Box − Since right input is 32-bit and round key is a 48-bit, we first need to expand right input to 48 bits. WebMar 5, 2024 · We will usually denote permutations by Greek letters such as π (pi), σ (sigma), and τ (tau). The set of all permutations of n elements is denoted by Sn and is typically referred to as the symmetric group of degree n. (In particular, the set Sn forms a group under function composition as discussed in Section 8.1.2).
