Consider a simple system with 8-bit block size. Assume the encryption (and decryption) to be as follows: If plaintext is LTRT and the key is LKRK, where LC,RC,LT, and RT are each 4 bits, then ciphertext= LC RC where LC=LK XOR RT; and RC=RK XOR LT; Plaintext and ciphertext are each 8 bits. Similarly, to decrypt ciphertext, we perform exactly the reverse operation where LT=RC XOR RK and RT = LC XOR LK. You are given the following 16-bit input A8B9 (in Hexa). You are provided IV as: A9 (Hexa). For CTR assume the stream of bits to be used for counter to be starting from 0001 and incremented by 1 every time; so, the stream would be 000100100011010001010110011110001001101010111100 1101111011110000000100100011010001010110011110001001101010111100110111101111 The 8-bit key to be used (where appropriate) is C5 (Hexa). Compute the encrypted output with (i) ECB (ii) CBC (iii) OFB (iv) CFB (v) CTR (with IV=0101)
