1. An affine cipher has the form c = (am+b) mod n. Suppose m is an integer between 0 and 25, each integer representing a letter. (a) Let n = 26, a = 3, and b = 123. What is the ciphertext corresponding to the phrase THIS IS A CIPHER MESSAGE. (b) A requirement for a cipher is that every plaintext letter correspond to a different ciphertext letter. If either a and b is not relatively prime to n, does the affine cipher meet this property? Either prove it does or present a counterexample.

Let F be a single round of a Feistel cipher operating on 64-bit blocks. That means an input a = (aL, aR) whereaL and aR are 32 bits long each, and F(aL, aR) = (aR, aL xor f(aR, k)). f is the Feistel cipher’s ”secret” function.Suppose that (aL, aR) and (bL, bR) are a pair of plaintexts such that aR xor bR = q for some number q.Consider what happens when we run two rounds of the Feistel Cipher on the input a, and two rounds of the Feistel Cipher on b:.(cL, cR)=F(F(aL, aR)), (dL, dR)=F(F(bL, bR)) ShowthatifcL =dL,thencR xordR =q.
The Feistel cipher is a symmetric block cipher encryption framework which is the basis of many modern day encryption algorithms. In this coursework you will implement a Feistel cipher system as a hardware component and as a software implementation. In a Feistel cipher the plaintext, P, to be encrypted is split into two equal size parts Lo and Ro such thatP = L,Ro- A function F is applied to one half of the plaintext, combined with a key, and the result is XOR'd with the other half of the plaintext. Feistel ciphers often employ multiple rounds of this scheme. In general the scheme works as follows, for all i = 0, .. . , n, L;+1= R; R+1 = L; © F(R, K;) To decrypt an encrypted message using this cipher we can apply the same procedure in reverse. For i = n, n – 1, . , 0, R; = L,+1 Lat1 L, = R,-1 e F(L,-1, K.) For this coursework we are interested in the 16-bit Feistel cipher which uses 4 rounds. The function F(A, B) = AOB. The keys are derived from a single 8-bit key Ko such that, Ko =…

Feistel block cipher. Assume a simple two-round Feistel block cipherwith an 8 bit key and a 16 bit block size. We write the keyas a decimal number (from 0 to 255) and the input as two decimalnumbers (also from 0 to 255). The key derivation is defined asKi = K + 75 ∗ i (mod 256), where 1 ≤ i ≤ 2. The Feistel functionis f(Ki,Ri−1) = 127 ∗ (Ki + Ri−1) (mod 256) where Ri−1 is the decimalrepresentation of the right 8 bits of the input block. Encrypt themessage (200, 33) with the key 10.
