The G7's Cyber Expert Group released a nonbinding roadmap urging financial institutions to transition to post-quantum cryptography before quantum computers can break current encryption. The framework outlines six phases from inventory and risk assessment to deployment and testing, with 2035 as a general completion target and 2030-2032 for critical systems. The roadmap emphasizes risk-based prioritization, standards-based approaches, cross-border collaboration, and close coordination with technology vendors. It addresses the "harvest now, decrypt later" threat where encrypted data collected today could be decrypted by future quantum systems, requiring institutions to act well before quantum computers become capable of breaking existing cryptographic methods.
