New Integrated proof Method on Iterated Hash Structure and New Structures
Authors: Duo LeiAbstract:
In this paper, we give a integrated proof
method on security proof of iterated hash structure. Based on the
proof method, we can distinguish the security of Merkel-Damagård
structure, wide-pipe hash, double-pipe hash and 3c hash and know the
requirement on true design compression function, we also give a new
recommend structure. At last, we give a new hash structure, MAC
structure, encryption model, and which use same block cipher round
function and key schedule algorithm and are based on Feistel structure, the security proofs on those structures are also given.
