Title:
LAB Form for Iterated Hash Functions
Authors: Xigen Yao
Abstract:In this paper,we proposed a efficient and laconic mode for iterative hash functions and tried to fix the flaws of the Merkle-Damgaard construction completely and certainly tried to prevent varieties of those generic attacks ,such as Multicollisions Attack,Second Preimage Attack and Herding Attack.The struc- ture of this new mode is different from HAIFA or any other proposal,it contains a new method “Locking Abutting Blocks”(LAB)with checksum ,it makes a larger size of connotative chaining value without requirements of intricate computing and larger memory and it allows for an online computation in one pass with a fixed memory independently .It’s also easy to avoid the generic attacks (presented by Praveen Gauravaram and John Kelsey) which apply on the hash functions with linear-XOR/additive checksum.
