A G7 Cybersecurity Working Group led by France’s ANSSI has urged governments and industry to accelerate migration to post-quantum cryptography (PQC), warning that quantum computers could eventually defeat widely deployed public-key encryption. The group said the risk is already material because adversaries can collect encrypted data now and decrypt it once cryptographically relevant quantum capabilities emerge, threatening secure communications, authentication, data integrity, and legally binding digital transactions.
The G7 recommends a phased, risk-based transition: inventory cryptographic assets, map system dependencies, prioritize critical data and services, and adopt quantum-safe products during regular technology refresh cycles. Its five priorities include greater awareness, national PQC strategies and supply chains, practical research and development, public-private coordination, and incorporation of PQC into cybersecurity requirements; it also stresses crypto-agility because candidate algorithms may evolve or prove vulnerable. The call was signed by the cybersecurity agencies of all G7 members and supported by the European Commission and ENISA.

The G7 published a call to action warning that quantum computing poses a near-term risk to public-key cryptography and urging a phased, risk-based transition to PQC. The document recommends cryptographic asset inventories, dependency mapping, prioritization of critical systems, quantum-safe procurement, and public-private collaboration; it was signed by the G7 national cybersecurity agencies and supported by the European Commission and ENISA.
A G7 cybersecurity working group prepared a report at the G7 Summit in France urging governments and organizations to accelerate preparation for migration to post-quantum cryptography.

The G7 Cybersecurity Working Group has called on governments and organizations across all sectors to begin preparing immediately for a transition to **post-quantum cryptography (PQC)**. The group highlighted the current “harvest now, decrypt later” threat: adversaries can collect encrypted information today and retain it until cryptographically relevant quantum computers can break existing public-key encryption, placing long-lived sensitive data at risk. The non-binding call prioritizes awareness, national strategies, research, public-private cooperation, and embedding PQC in cybersecurity requirements. Organizations should begin with a cryptographic inventory, defined ownership, limited pilots, crypto-agile architecture, hybrid standardized deployments, and PQC-focused procurement. EU member states are expected to have initiated national PQC strategies by the end of 2026, while high-risk environments—particularly critical infrastructure—should transition as early as possible and no later than the end of 2030; delayed adoption could also affect supplier eligibility for public-sector and other contracts.

Concerns about **quantum computing** undermining today’s cryptography are influencing both market behavior and policy planning. A Jefferies strategist reportedly removed a 10% **Bitcoin** allocation from a model portfolio, citing the risk that future quantum advances could eventually compromise cryptographic protections underpinning cryptocurrencies (e.g., long-term concerns around breaking schemes associated with Bitcoin’s security model, which relies on `SHA-256` hashing and public-key cryptography for ownership control). The decision reflects broader investor anxiety that a surprise cryptographic break could rapidly erode confidence and value across crypto markets. In parallel, the **G7 Cyber Expert Group** published a roadmap calling for the financial sector to complete **post-quantum cryptography (PQC)** implementation by **2034**, emphasizing early-stage quantum risk awareness, sensitive data and critical system mapping, and building detailed inventories that include third-party dependencies. The roadmap recommends beginning migration activities in the 2026–2029 window, progressing to quantum-resistant solutions through 2034, and prioritizing **cryptographic agility** so organizations can adapt as standards and threats evolve. Separate reporting on a **58% increase in ransomware victims in 2025** describes a fragmented ransomware ecosystem and sector targeting trends, but it is not directly tied to quantum-driven cryptographic risk or PQC migration planning.

Cybersecurity leaders are raising alarms about the accelerating timeline for quantum computing to break current public encryption methods, a milestone known as Q-Day. Experts warn that Q-Day could arrive as soon as 2030, threatening to undermine the core trust mechanisms of the internet, including HTTPS, digital certificates, and public-key infrastructure. In response, governments and industries are developing plans to transition to post-quantum cryptography (PQC), but concerns remain that critical sectors such as banking, healthcare, and government may not be fully prepared in time. One of the earliest operational changes in anticipation of quantum threats is the reduction of SSL/TLS certificate lifespans to 47 days. This move, aligned with evolving browser requirements and NIST guidance, is designed to improve crypto agility and security hygiene, helping organizations adapt to a future where static cryptography is no longer viable. Security executives emphasize the need for urgent action, drawing parallels to the unpreparedness seen during the rapid adoption of AI, and stress that building operational readiness for PQC is now a strategic imperative for digital trust and business continuity.
