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 RC4 is a stream cipher standard that was used widely on the Internet.

Answer rating: 100% (QA)

The number of bits used for encryption in the RC4 algorithm depends on the size of the internal state array S In the provided code the size of S is 256 bytes Since a byte is 8 bits 256 bytes is equal ... View the full answer
