Description
QKD is a landmark of how quantum resources allow us to implement cryptographic
functionalities with a level of security that is not achievable only with classical resources.
However, key agreement is not sufficient to implement all functionalities of interest, and it is
well-known that they cannot be implemented with perfect security, even if we have access
to quantum resources. Thus, computational assumptions are necessary even in the quantum
world.
In this talk, I will cover recent examples that even in the computational setting, quantum
resources may give an advantage in the required assumption. More concretely, I will talk
about quantum implementations of multi-party computation and public-key encryption
under weaker computational assumptions than their classical counterparts. Moreover, I will
discuss new cryptographic assumptions that are inherently quantum, which have changed
the landscape of the feasibility of cryptographic primitives in the quantum world.
