For anyone wondering about the acronyms above, ECB is Electronic Codebook, CBC is Cipher-block Chaining, and IV is an Initialization Vector used in CBC. IND-CPA is Indistinguishability under chosen-plaintext, a method of attack. These are explained at [1] and [2] [1] http://en.wikipedia.org/wiki/Block_cipher_mode_of_operation http://en.wikipedia.org/wiki/Block_cipher_mode_of_operation [2] http://en.wikipedia.org/wiki/Ciphertext_indistinguishability http://en.wikipedia.org/wiki/Ciphertext_indistinguishability
