October 16, 2003 - The Cryptanalytical Time-Memory Trade-Off: how fast can you go?
by Philippe Oechslin
| Abstract: | Since Martin Hellman introduced the Cryptanalytical Time-Memory
Trade-Off in 1980, only few optimisation have been suggested. At Lasec
we have developed a new way of organizing the trade-off which makes it
an order of magnitude faster. Moreover the new trade-off has a more
regular structure, which reduces precomputation time, allows for a
better analysis of its performance and opens up possibilities for
other improvements.
We will present the original trade-off, the new version that was
presented at Crypto '03 (with the 5 second windows password cracker
demo) and new directions for creating an even more efficient
trade-off. |
