ABSTRACT:
Some embodiments of a method and apparatus for encrypting and decrypting data have been presented. In one embodiment, a current initialization vector (IV) is generated based on a previous block of plaintext enciphered. Then a current block of plaintext is combined with the current IV to create a temporary block. An encipher may encipher the temporary block to generate a current block of ciphertext.
