🛡️ Q-Day Cybersecurity Roadmap & Timeline

📊 Timeline: Preparing for Q-Day

Year	Milestone
2022–2024	NIST finalizes post-quantum cryptographic algorithms (Kyber, Dilithium, etc.)
2025–2026	Tech companies and vendors begin integrating PQC into TLS, VPNs, software signing
2026–2027	Early adoption in government and critical infrastructure; hybrid crypto starts rolling out
2028–2030	Broad industry migration begins; crypto-agility becomes standard
2030–2040	Probable range when scalable quantum computers emerge (Q-Day)
2040+	Full replacement of vulnerable algorithms across infrastructure

📚 What is Q-Day?

Q-Day (Quantum Day) is the moment quantum computers become powerful enough to break classical encryption (RSA, ECC, DH) using Shor’s Algorithm. This could instantly compromise today's digital security.

🧭 Roadmap to Q-Day Readiness

🔹 Phase 1: Awareness & Assessment (Now)

[ ] Inventory cryptographic assets (TLS, SSH, VPNs, secrets)
[ ] Identify RSA, ECC, or DH usage
[ ] Train teams on PQC and crypto-agility

🔹 Phase 2: Risk Analysis & Planning

[ ] Classify systems by sensitivity and exposure
[ ] Assess long-term risk areas (health/legal/firmware)
[ ] Design crypto-agile architectures

🔹 Phase 3: Transition Planning (2025–2026)

[ ] Track NIST PQC developments
[ ] Test hybrid encryption (RSA + PQC)
