i need to solve this Q in information secutry with steps and i will post example of steps

this example of steps:

Suppose that the state vector S is 4 bits. We will operate on 3-bits of plaintext at a time. Assume that we use a 3 3-bit key, K, and plaintext P as below: K=[221]P=[153] Encrypt P using RC4 method? S-RC4: Simplified RC4 - instead of the full 256 bytes, - we will use 83-bits. - the state vector S is 83 3-bits. - We will operate on 3-bits of plaintext at a time - S can take the values 0 to 7, which can be represented as 3 bits. - Example: - Assume we use a 43-bit key, K, and plaintext P as below: E=[1236]p=[1222] S-RC4 Example E=[1236]P=[1222] - The first step is to generate the stream. - Initialiet the state wector 5 and temporary vector T. +5=101234567+T=123612363 - Now pertorm the leitial permutation on 5. S-RC4 Example K=[1236] P=[1222] - Now we senerate 3-bits at a time, k, that we XOR with each 3-bits of plaintert to produce the cipherteot. The 3-bits k is generated by: i.f=0iwhal=(Erue)f1=(1+1)mode.3=(5+a(2])nodenSo[23746015]k=ce[1]+a[j]+sose+ mutation of 5 gives: So to encrypt the plainsext stream F with key K with our simplified ACt stream we iret C i P=[1.22.2]K=[1236]C=[432.3] Or in binary F=601010010010K=001010011110C100011010011
