Physics, Topology, Logic and Computation: A Rosetta Stone (2009)
In physics, Feynman diagrams are used to reason about quantum processes. In the 1980s, it became clear that underlying these diagrams is a powerful analogy between quantum physics and topology:...
Physics, Topology, Logic and Computation: (2009)
A Rosetta Stone, John C. Baez, Mike Stay
Category theory is a very general formalism, but there is a certain special way that physicists use categories which turns out to have close analogues in topology, logic and computation. A category...
The Twofish Team's Final Comments on AES Selection (2000)
Bruce Schneier, John Kelsey, Doug Whiting, David Wagner, Chris Hall, Niels Ferguson, ...
Introduction In 1996, the National Institute of Standards and Technology initiated a program to choose an Advanced Encryption Standard (AES) to replace DES [NIST97a]. In 1997, after soliciting public...
Improved Cryptanalysis of Rijndael (2000)
Niels Ferguson, John Kelsey, Stefan Lucks, Bruce Schneier, Mike Stay, David Wagner, ...
We improve the best attack on Rijndael reduced to 6 rounds from complexity 2^72 to 2^44 . We also present the first known attacks on 7- and 8-round Rijndael. The attacks on 8-round Rijndael work for...
Cryptanalytic Progress: Lessons for AES (2000)
John Kelsey, Niels Ferguson, Bruce Schneier, Mike Stay
this paper, we review cryptanalytic progress against three well-regarded block ciphers and discuss the development of new cryptanalytic tools against these ciphers over time. This review illustrates...
