The preliminаry оperаtiоns оf RC4 cаn summerized as (1) Initialization and (2) Initialization Permutation of Array S.For a RC4 with the key K[0] = 00000011= 3 K[1]=00000111 = 7 K[2]=00001111= 15, the keylen = 3. Please do the following:Derive the first 8 elements of array T after the following initialization. for i = 0 to 255 do S[i] = i; T[i] = K[i mod keylen]; 2. Calculate the first 5 elements S[0], S[1], S[2], S[3], and S[4] of array S after the following initial permutation of S. j = 0; for i = 0 to 255 do j = (j + S[i] + T[i]) mod 256; Swap(S[i], S[j]);
