Data encryption is a key element of cyber security, protecting data in transit to avoid unauthorised access (eavesdropping and tampering). However, current widely used algorithm-based public-key encryption methods are at risk from the potential of quantum computers to break encryption. Quantum key distribution (QKD) may provide one potential approach to address this risk in part, but there are other approaches and, at present, the UK National Cyber Security Centre (NCSC) advises post-quantum cryptography (PQC) as the preferred approach.<\/p>\n\n\n\n

The Cyber Security and Digital Identity Directorate of DSIT commissioned Technopolis to conduct a study on QKD technology and its cyber security implications.<\/p>\n\n\n\n

The objective is to inform if any policy measures may be appropriate with the aim of protecting UK networks that use, or will use, QKD, while enabling them to take advantage of the technology\u2019s cyber security capabilities.<\/p>\n\n\n\n
