Title:
Variants of the Distinguished Point Method for Cryptanalytic Time Memory Trade-offs (Full version)

Authors: Jin Hong, Kyung Chul Jeong, Eun Young Kwon, In-Sok Lee, Daegun Ma

Abstract:

The time memory trade-off (TMTO) algorithm, first introduced by Hellman, is a method for quickly inverting a one-way function, using pre-computed tables. The distinguished point method (DP) is a technique that reduces the number of table lookups performed by Hellman’s algorithm. In this paper we propose a new variant of the DP technique, named variable DP (VDP), having properties very different from DP. It has an effect on the amount of memory required to store the pre-computed tables. We also show how to combine variable chain length techniques like DP and VDP with a more recent trade-off algorithm called the rainbow table method.
