WORKSHOP HASH & STREAM
On February 1 and 2, 2007, the workshop '' Hash & Stream"
on the state of the art in cryptanalysis of hash
functions and stream ciphers was held at the Department of Mathematics
of the University of Salzburg (see
The workshop was organized by Peter Hellekalek.
Below, we offer the slides of the talks:
- Introductory talk on cryptographic hash functions and their cryptanalysis
by Vincent Rijmen (TU Graz),
- Recent attacks on hash functions, by Vincent Rijmen,
- Most recent attacks on SHA-1 , by Christian Rechberger (TU Graz),
- Practical impact of the recent attacks and what will happen now,
by Norbert Pramstaller (TU Graz),
of alternative hash functions, by Florian Mendel (TU Graz),
- Design and
recent analysis of eSTREAM candidates, by Willi Meier, (UAS, Aargau).
RANDOM NUMBER GENERATORS
Cryptographic random number generators will have to be unpredictable,
in addition to many other randomness properties that are required.
This rules out most RNGs that are used in stochastic simulation.
- The National Institute of Standards and Technology (NIST) is
developing a battery of statistical tests to detect "non-randomness"
in binary sequences. The so-called NIST-battery of tests has become
a de-facto standard for cryptographic generators, see their webpage
Number Generation and Testing.
As we have indicated on our
any new standard will have to consider the
TESTU01 library of L'Ecuyer and Simard (Montreal University) as a basis.
