Abstract:

Two MACs which are based on tweakable block ciphers are constructed:TXOR and PMAC.Then their corresponding stateful,randonmized,and determined algorithms are studied respectively and the concrete security bounds are given.

Key words: block cipher, tweakable block cipher, MAC, mode of operation
