[en] We describe the application in security of shells of
Cholesteric Liquid Crystals (ChLCs). Such shells have a diameter
in the microns range and can be gathered in hundreds in a
surface area as small as a nail’s head. Because of their structural
properties, a bundle of them reflects light, creating colorful
patterns that we argue to be unique and computationally hard
to predict. We argue also that the bundle itself is unclonable.
These are typical properties of Physically Unclonable Functions,
a family to which shells of ChLCs belong too. Herein we discuss
their physical and security properties and their potential use in
object authentication.
