Governments have established a deadline of 2035 for the complete migration to post-quantum cryptography, necessitating the phase-out of RSA and ECC. This requirement applies not only to public sector systems but also to contractors and industries that handle sensitive or regulated data. The transition process is intricate and will span multiple years, demanding thorough planning, system audits, and coordination with various infrastructure and vendors. As a result, entities must begin planning and preparing for the transition to post-quantum cryptography immediately, taking into account the complexity of the process and the need for coordination with multiple stakeholders1. The urgency of planning for post-quantum cryptography has increased due to recent quantum developments, making it essential for practitioners to prioritize migration to ensure the long-term security of their systems. This deadline has significant implications for the security of sensitive data, and meeting it will require careful planning and execution.
