A Practical Attack on the Root Problem in Braid Groups
Authors: Anja Groch, Dennis Hofheinz, Rainer SteinwandtAbstract:
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 within seconds, extract the secret key of an authentication system based on the root problem in braid groups.
