Entanglement-Based Multiparty QKD System
Overview
At the Technical University of Berlin, we have installed the ELVIS 1500 system with an additional PAM 800 module, developed by Quantum Optics Jena, to explore the potential of entanglement-based multiparty Quantum Key Distribution (QKD). This system was set up in December 2023 and serves as a pivotal element of our research into quantum communication and security.
Research Focus
1- Security assessment of QKD System
As part of the Q-net-Q project, our research aims to enhance the security of QKD systems through a comprehensive evaluation of their vulnerabilities. We conduct a series of attacks on the system to analyze potential information leakage and identify security weaknesses. This analysis is crucial for developing essential protocols and strategies for pre-certifying the security of QKD systems.
2- Cryptographic Protocols Beyond QKD
In addition to evaluating vulnerabilities, our research explores the feasibility of implementing advanced cryptographic protocols into a QKD system. We are particularly interested in:
- Conference Key Agreement: Facilitating secure multi-party communication.
- Coin Flipping: Ensuring fair and unbiased digital agreements.
- Bit Commitment: Securing transactions and commitments in digital spaces.
These efforts involve detailed investigations of the necessary software modifications required to integrate these cryptographic primitives into the existing QKD infrastructure.
Goals and Use Cases
Goal: To enhance the security and functionality of QKD systems by identifying vulnerabilities and exploring additional cryptographic capabilities.
Realized Use Cases: Trusted QKD-ICT setups that ensure robust security for future quantum communications.
