CISA and G7 Cyber Security Working Group Partners Release Post-Quantum Era Call to Action

Today, the Cybersecurity and Infrastructure Security Agency (CISA) and Group of Seven (G7) Cyber Security Working Group members released Preparing for the Post-Quantum Era: A Call to Action highlighting the urgent need for organizations and governments to begin transitioning to post-quantum cryptography (PQC) to protect sensitive data and critical assets from emerging quantum computing threats.

Unlike traditional computers that process data in binary digits or “bits” which have only one of two possible values, quantum computers use quantum bits or “qubits” which can exist in a combination of both values at the same time—making it possible for quantum computers to problem-solve faster than traditional computers. As quantum computing advances, these computers will be able to break public-key cryptography widely used to protect sensitive data and communications.

Malicious cyber threat actors are already intercepting and storing public-key encrypted data today in “harvest now, decrypt later” strategies. Once cryptographically relevant quantum computers (CRQCs) are available to malicious cyber threat actors, they will be able to target organizations still using public-key encryption with the potential to impersonate trusted entities, compromise equipment, and access confidential data.

This call to action urges organizations not to wait for CRQCs to become available, but to prioritize PQC migration and begin identifying critical assets, mapping dependencies, and developing phased transition plans aligned with their national cybersecurity authorities. Read the call to action to learn more about PCQ migration and the five priority areas to consider when planning.
