The Propagating Cipher Block Chaining Mode Pcbc Is Designed To Cause Small Chang

The propagating cipher block chaining mode (PCBC) is designed to cause small changes to propagate indefinitely when decrypting (and encrypting). The encryption algorithm is described as follows:Ci = EK [Pi ⊕ Pi-1 ⊕ Ci – 1], P0 ⊕ C0 = IV
