DESCRIPTION:Speakers: Ilinca Radulescu\n\nWe introduce a novel framework f
 or constructing cryptographic schemes in the setting of category theory. S
 imply put\, a category is defined as a set of objects and a set of morphis
 ms\, which obtain a list of specific properties. Since we are interested i
 n obtaining a cryptographic category\, we also introduce a list of computa
 tional axioms that the framework must satisfy. A key concept is the finger
 print\, a collection of maps from the homset to a set $\\mathcal{M}$\, wit
 h some special properties. Using this framework\, we then show how to buil
 d a hash function\, a signature scheme and a Chameleon-Hash function.\n\nh
