Abstract
In [12] Vaudenay presented side-channel attacks on the CBC encryption mode cipher under the padding oracle attack models, which enable an adversary to determine the correct message with knowledge of ciphertext. Black and Urtubia generalized these attacks in several directions, considering various padding schemes [4]. In this paper we extend these attacks to other kinds of modes of operation for block ciphers. Specifically, we apply the padding oracle attacks to multiple modes of operation with various padding schemes. As a results of this paper, 12 out of total 36 double modes and 22 out of total 216 triple modes are vulnerable to the padding oracle attacks. It means that the 12 double modes and the 22 triple modes exposed to these types of attacks do not offer the better security than single modes.
