Quantum Key Infrastructure

The research described in this project proposes a very realistic and Quantum Computing resilient key distribution networking protocol to enable highly secure and efficient information flow. On one hand, the protocol provides unconditional one-time-pad based encryption; on the other hand, it is based on information-theoretic concepts that can be cost-effectively implemented today to establish Quantum Key Infrastructure (QKI) that somewhat resembles already existing Public Key Infrastructure (PKI). The PKI to a large extent could be used to enable QKI. The protocol is of high relevance given the threat that quantum computers can pose on present and future IT infrastructures.
