Abstract

It is indispensable for social deployment of quantum key distribution to certificate the security on the installed systems, or implementation security. In this talk, we will present several case studies on the implementation security certification.

Implementation Security Certification of Decoy‐BB84 Quantum Key Distribution Systems

Akihisa Tomita

Abstract One of the most important obstacles for the social deployment of Quantum Key Distribution (QKD) systems is the lack of standards for security certification. Proper selection of application will circumvent other obstacles, such as cost, key generation distance, and rate. Nevertheless, security certification of real systems, or “implementation security certification” is indispensable. Such certification should be clear and tractable for non‐experts and should be performed with standardized characterization methods. Otherwise, the potential users cannot adopt the QKD system with confidence, because the highest level of security is what QKD appeals. This report discusses the process of the implementation security certification and the requirements for device characterization. It also presents several case studies on the requirements and experimental characterization of QKD devices for the security certification.

Quantum Key Distribution in the Real World

Akihisa Tomita

Continuing efforts have been made to develop practical quantum key distribution (QKD) systems on the installed fiber networks since early 2000s [1]. Recently, several groups have demonstrated high-speed QKD systems [2,3] with GHz-clock frequency working stably on the installed-fiber networks [4-7]. Along with the hardware development, an efficient key management protocol [7] has been implemented to construct a QKD platform to supply information-theoretically secure key for multiple applications. The highly available QKD platform is expected to promote social deployment of the QKD technology.
