Challenges in the Transition towards a Quantum-safe Government

What is it about?

The computation power of quantum computers introduces new security threats in Public Key Infrastructure (PKI), a system used by many governments to secure their digital public services and communication. This calls for an inevitable need for governments to be quantum-safe (QS) by modifying their PKI systems to be resistant to the attacks of quantum computers. However, there is limited academic literature on a QS PKI system, and in this limited literature, the transition challenges are perceived as exclusively technological. This paper aims to create a structured overview of challenges when transitioning to a QS PKI system.

Why is it important?

A deeper understanding of the challenges in transitioning towards a quantum-safe (QS) PKI system may provide us with important insights into QS transition. However, there is no structured overview of the challenges when transitioning from the current PKI system to one that is quantum-safe. Prior literature on a QS PKI system largely focuses on technological challenges by addressing the limitation of a legacy system and the development of QS cryptographic algorithms
