Description
The importance of cryptography has become more prevalent in contemporary communication and the commercial use of Quantum Key Distribution (QKD) is now a realistic option for fibre networks. Long-range, free-space QKD and miniaturised, personal QKD devices are emerging fields of research aiming towards future commercial use. Previously, a handheld QKD device was developed using the COW protocol to exchange the encryption key between the sender and receiver [1]. An optical synchronisation system was developed for the handheld device establishing real time synchronisation between the sender and receiver.
This paper will investigate the viability of other synchronisation techniques appropriate for a handheld QKD device. The first technique will use asynchronous communication to establish communication between the sender and receiver. The second technique will use a radio channel to establish synchronisation, based on the methods designed in [2]. The tracking capabilities of the radio synchronisation method will assist a handheld QKD device in establishing a connection between devices that are not pre-aligned.
