WebQuestion: Part 1 Suppose Alice encrypts blocks P1, P2 and P3 using CBC mode (22.7.3 Cipher Modes). The initialization vector is C0. The encrypt and decrypt operations are E(P) = C and D(C) = P. We have C1 = E(C0 XOR P1) C2 = E(C1 XOR P2) C3 = E(C2 XOR P3). Suppose Mallory intercepts C2 in transit, and replaces it with C2’ = C2 XOR M; C1 and ... WebJun 7, 2002 · C1 +C2 =P1 +K +P2 +K =P1 +P2. Examining the bit patterns of P1 + P2 can easily result in recovering one of the plaintexts. The latter can then be XORed with its ciphertext to yield the keystream. By transforming one bit at a time the XOR operation lends itself well to a class of encryption algorithms known as stream ciphers.
