  Low-dimensional topological objects, such as knots and braids, have become
prevalent in multiple areas of physics, such as fluid dynamics, optics, and
quantum information processing. Such objects also now play a role in
cryptography, where a framed knot can store encoded information using its braid
representation for communications purposes. The greater resilience of
low-dimensional topological elements under deformations allows them to be
employed as a reliable framework for information exchange. Here, we introduce a
challenge-response protocol as an application of this construction for
authentication. We provide illustrative examples of both procedures showing how
framed links and braids may help to enhance secure communication.
