Transitioning Towards Quantum-Safe Government: Examining Stages of Growth Models for Quantum-Safe Public Key Infrastructure Systems

Abstract

Public Key Infrastructures (PKIs) provide digital public services and communication by securing information-sharing and strong credentials for digital identity management to individuals, businesses, and government agencies. While cryptographic algorithms that current PKI systems depend on are mostly resilient against hacks and other threats launched from computers we use today, the advancement of quantum computing technology introduces new security threats. This calls for current PKI systems to be modified with quantum-safe cryptographic algorithms. However, transitioning to Quantum-safe (QS) PKI systems remains complex, and the challenges are socio-technical. The research aims to guide organizations transitioning towards QS PKI systems. In doing so, we will deconstruct the QS transition into a series of stages and paths using growth models and examine how organizations can transit over time towards QS PKI systems.
