The power of quantum adversaries

The power of quantum adversaries
Abstract:
Tato diplomová práce analyzuje schéma jež využívá několik kvantových kryptografických protokolů v bounded quantum storage modelu. Představujeme nové ekvivaletní schéma s využitím entanglement sampling a navrhujeme nový způsob limitování kvantové paměti protivníků v tomto modelu. Limitujeme tuto pamět pomocí relativní kvantové entropie. Navrhujeme hypotézu o relaci neurčitosti v tomto schématu. Dokazujeme …more
Abstract:
This thesis investigates a scheme recurring in several quantum cryptography protocols in the bounded quantum storage model. We introduce a new equivalent scheme using entanglement sampling and propose a new way of bounding the quantum memory of the adversaries in this model. We bound the quantum memory of adversary in this mode using conditional quantum min-entropy. We hypothesize a new entropic uncertainty …more
