Summary:
|
The current security model is based on security perimeter protection which trusts internal users in the perimeter. It can be venerable when internal user’s account is compromised or VPN is attacked. Also cyber attacks are increasing and their attack methods are also advancing including supply chain attack. Also, as cloud environment are expanding and remote work become routine, on-premise security policy alone cannot protect. Zero trust security model can fill the gaps that the current security model lacks.
Quantum cryptography alone cannot solve potential cyberattacks by quantum computers due to the above-mentioned issues. Integrated security model of QKD and zero trust architecture is essential to protect IMT-2020/2030, and cloud networks and computing environment from advanced future cyberattacks. Zero trust security model can become a core security model due to the following: (1) internal and external threat protection by entire access request authentication, (2) overcoming perimeter protection limitation, (3) internal attack protection by Principle of Least Privilege (POLP), (4) enhancement of quantum security model enabled by AI based anomaly detection.
This draft technical report studies the technical implications of applying zero trust architecture into QKDN for quantum safe security of future networks including IMT-2020 and IMT-2030 networks. It also identifies standardization considerations as a result.
