could you please code this on notepade. The Feistel cipher is a symmetric block cipher encryption framework which is the basisof many modern day encryption algorithms. In this coursework you will implement aFeistel cipher system as a hardware component and as a software implementation. In aFeistel cipher the plaintext, P, to be encrypted is split into two equal size parts Lo andRo such thatP = L,Ro- A function F is applied to one half of the plaintext, combinedwith a key, and the result is XOR'd with the other half of the plaintext. Feistel ciphersoften employ multiple rounds of this scheme. In general the scheme works as follows, forall 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 procedurein reverse. For i = n, n – 1, . , 0,R; = L,+1Lat1L, = 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 = b,b6b;b4b3bzbi boK1 = b6b5b,b3b2bibob,K2 = b;b,bzb,b,bob-b6K3 = b,b3b2b1bob-b6b51 2. Write a program in HACK assembly, without using symbols, that implements thedescribed Feistel encryption system. The initial key, Ko, will be stored in RAM[1],and the 16-bit plaintext will be stored in RAM[2]. The result of the encryptionshould be stored in RAM[0]. Your solution should be submitted in a file called"FeistelEncryption.asm"You may use any RAM locations not specified in the description for intermediatevariables.
