A New Cryptanalytic Time/Memory/Data Trade-off Algorithm

In 1980, Hellman introduced a time/memory trade-off (TMTO) algorithm satisfying the TMTO curve TM = N, where T is the online time, M is the memory and N is the size of the search space. Later work by Biryukov-Shamir incorporated multiple data to obtain the curve TMD = N, where D is the number of data points. In this paper, we describe a new table structure obtained by combining Hellman’s struct...

Cryptanalytic Time-Memory Tradeoff for Password Hashing Schemes

A cryptanalytic technique known as time-memory tradeoff (TMTO) was proposed by Hellman for finding the secret key of a block cipher. This technique allows sharing the effort of key search between the two extremes of exhaustively enumerating all keys versus listing all possible ciphertext mappings produced by a given plaintext (i.e. table lookups). The TMTO technique has also been used as an eff...

Once Upon a Time-Memory Tradeoff

Once upon a time, I worked for a small startup company. The pay was excellent, but the hours were long and vacation time was limited. I currently work as a college professor, where the pay is not-so-good but the hours and vacation time are excellent. For several years, I also worked for the government, where the pay is reasonably good and the hours and vacation time are reasonably good. So, it ...

Variants of the Distinguished Point Method for Cryptanalytic Time Memory Trade-Offs

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...

Three Years of Evolution: Cryptanalysis with COPACOBANA

In this paper, we review three years of development and improvements on COPACOBANA, the probably most popular, reconfigurable cluster system dedicated to the task of cryptanalysis. Latest changes on the architecture involve modifications for larger and more powerful FPGA devices with dedicated 32 MB of external RAM and point-to-point communication links for improved data throughput. We outline ...
