Trapdoor DDH groups and some open problems
Dr Steven Galbraith
Royal Holloway University of London
A trapdoor DDH group is a group for which a user
with some private information can solve the decision-Diffie-Hellman
problem.
We will discuss this idea and give a realisation of it.
The talk will then digress into a discussion of whether or not one
can securely disguise algebraic groups.
