Checking whether a particular group has an efficient, faithful representation as a matrix group
There are cryptographic protocols being developed for non-abelian groups. For some protocols it is necessary to know whether the group has an efficient representation as a matrix group (say, a matrix ...

Coppersmith attack on NTRU and non-commutativity
In this paper, Coppersmith and Shamir used lattice reduction to attack NTRU. At the very end of the paper, they note that developing non-commutative variants of NTRU would be wise, in light of their ...

What are the typical instance parameters of non-commutative cryptographic schemes?
Recently, I grew a tremendous interest for public-key cryptography based on "groupoids", and collaborated with someone on this topic. What I notice afterwards, is that there had been a huge ...
