Question: Given the Cipher Block chaining algorithm: Ci-1 = IV Ci = Ek(Pi XOR Ci-1) Encrypt the binary message (P0-P4) where the plaintext message is broken
Given the Cipher Block chaining algorithm: Ci-1 = IV Ci = Ek(Pi XOR Ci-1) Encrypt the binary message (P0-P4) where the plaintext message is broken into 8 bit blocks using the key (Ek) and the initialization vector (IV) shown. Assume that the Simple Cipher (SC) or encryption is performed in two steps: Invert all the bits in the block. Rotate the inverted bits six bits to the left. The inputs are: IV = 3Fx Key = 2Ex P0 = 4Fx P1 = 32x P2 = F7x P3 = 91x What is C3?
