Abstract

As quantum computing progresses, traditional cryptographic systems face the threat of obsolescence due to the capabilities of quantum algorithms. This paper introduces the Quantum-Ready Architecture for Security and Risk Management (QUASAR), a novel framework designed to help organizations prepare for the post-quantum era. QUASAR provides a structured approach to transition from current cryptographic systems to quantum-resistant alternatives, emphasizing technical, security, and operational readiness. The framework integrates a set of actionable components, a timeline for phased implementation, and continuous optimization strategies to ensure ongoing preparedness. Through performance indicators, readiness scores, and optimization functions, QUASAR enables organizations to assess their current state, identify gaps, and execute targeted actions to mitigate risks posed by quantum computing. By offering a comprehensive, adaptable, and quantifiable strategy, QUASAR equips organizations with the tools necessary to future-proof their operations and secure sensitive data against the impending rise of quantum technologies.
