In this paper we study a novel computational problem called
the Hidden Root Problem, which appears naturally when considering
fault attacks on pairing based cryptosystems. Furthermore, a variant of
...
A Practical Attack on the Root Problem in Braid Groups
Practical Attack Root Problem Braid Groups
2009/3/19
Using a simple heuristic approach to the root problem in braid
groups, we show that cryptographic parameters proposed in this context must
be considered as insecure. In our experiments we can, often...
On an authentication scheme based on the Root Problem in the braid group
authentication scheme Root Problem braid group
2009/2/23
Lal and Chaturvedi proposed two authentication schemes
based on the difficulty of the Root Problem in the braid group. We
point out that the first scheme is not really as secure as the Root
Problem...
