The effort in reducing the area of AES implementations has largely been focused on Application-Specific Integrated Circuits (ASICs) in which a tower field construction leads to a small design of the A...

The Discrete Logarithm Problem is at the base of the famous Diffie Hellman key agreement algorithm and many others. The key idea behind Diffie Helmann is the usage of the Discrete Logarithm function i...
For large ranks, there is no good algorithm that decides whether a given lattice has an orthonormal basis. But when the lattice is given with enough symmetry, we can construct a provably deterministic...
Breaking the Symmetry: a Way to Resist the New Differential Attack

sflash had recently been broken by Dubois, Stern, Shamir,
etc., using a differential attack on the public key. The C¤− signature
schemes are hence no longer practical.
