A couple questions about Applied Cryptography (Second Edition)
1. What on earth is a Neural Net?
2. Consider the Chinese Lottery attack vs a processor bank.
ADVANTAGES
Distributed computing, no easy bombing target.
DISADVANTAGES
39% inefficient
Need specialized hardware [for speed] or transmission of alogrithms
for any specific alogrithm
Not on all the time
If value(crack) * cracks/chip > cost of chip, then why not have
the gov buy the chips? Its probably cheaper that way.
3. How does one cryptoanalyize a Feistel Network? Is there a general
method?
4. Does there exist an n such that a keyspace of 2^n is trivial to crack
[ie a matter of miniutes] on a PC but is difficult to crack for a
big commercial company or even a major government? [this question
relates to Merkle's puzzles, when a 40-bit key seems a bit weak.]
5. Is there an errata yet?
