Post-quantum cryptography today

Takeaways 

• The advent of powerful quantum computers risks threatening the security of current cryptography. Post-quantum cryptography methods can resist cyberattacks from both classical and quantum computers. 
• The potential disruptions to cybersecurity brought by quantum computers pose profound, cross-cutting risks to areas such as national security, health, finance, and critical infrastructures.
• It is urgent to migrate current digital systems to post-quantum cryptography already today, to avoid ‘store now, decrypt later’ risks related to sensitive data.
• Public organisations and critical sectors are encouraged to initiate transition plans promptly, so that high-risk systems are migrated to post-quantum cryptography by 2030.
