Abstract:
As threats in the maritime domain diversify, securing data transmission becomes critical for underwater wireless networks designed for the surveillance of critical infrastructure and maritime border protection. This has sparked interest in underwater Quantum Key Distribution (QKD). In this study, a fully functional BB84 QKD system is developed as a solution to the emerging security need of underwater wireless communication systems. The QKD unit is built on a hybrid computation system consisting of an Field Programmable Gate Array (FPGA) and an on-board computer (OBC) interfaced with optical front-ends. A real-time photon counting module is implemented on FPGA. The transmitter and receiver units are powered with external UPS and all system parameters can be monitored from the connected computers. The system is equipped with a visible laser and an alignment indicator to validate successful manual alignment. Secure key distribution at a rate of 100 qubits per second was successfully tested over a link distance of 7 meters.
Bio:
Burak Kebapci studied Electrical & Electronics Engineering Major and Computer Networks Minor at the Bahcesehir University in Istanbul, Turkey. He is accepted for M.Sc degree in Electrical & Electronics Engineering from Ozyegin University in 2015. He joined Center Of Excellence in Optical Wireless Communication Technologies (OKATEM) in 2015 as a project engineer. In 2016 he became the Engineering Team Lead of OKATEM. He won National Instruments Engineering Impact Award in the category of RF/Mobile Communications in 2017. The same year he graduated with an M.Sc degree and co-founded Hyperion Technologies and became the Chief Technology Officer (CTO) of the company. Later, he started pursuing a Ph.D. in Electrical & Electronics Engineering at Özyegin University in 2017.
