RC4 is a stream cipher standard that was used widely on the Internet. Read the below pseudocode for its initialization phase and cipher bitstream generation phase: // Initialization byte key [N]; byte K[256]; // input key of the algorithm (E.g., N = 16) // keying material. byte s[256]; // internal states. for i = 0 to 255 s[i] = i K[i] key [i (mod N)] j = 0 for i = 0 to 255 j (j+s[i] + K[i]) mod 256 swap (S[i], s[j]) i = j = 0 // Cipher Bitstream Generation i (i+1) mod 256 = j(js[i]) mod 256 swap (S[1], S[j]) t(s[i]s[j]) mod 256 cipherstream = s[t] How many bits will be used for encryption finally? Explain the relation of the arrays key and S, which leads to the selection of these bits. Activate Win Go to Settings to
