Outline of Research at the Start

Classical key distribution protocols, which are based on the mathematical complexity of cryptography techniques, can be soon compromised. Capitalizing on the law of quantum physics, QKD has been considered as a promising method with proved implementations for fixed networks. This proposal aims to study the proposal of QKD systems for wireless networks based on the FSO technology and high-altitude platforms. We focus on solving both fundamental theory as well as system, protocol designing issues to achieve a reliable and efficient key distribution method for the future wireless networks.
