Urgent Need For Post-Quantum Cryptography To Counter Emerging Threats

The federal government’s cybersecurity is facing an unprecedented threat from quantum computing, with Cryptographically Relevant Quantum Computers (CRQCs) expected to emerge by 2029. This development may enable adversaries to decrypt sensitive data, posing a significant risk to national security. The Cybersecurity and Infrastructure Security Agency (CISA) is struggling to respond to emerging threats due to a diminished capacity. However, post-quantum cryptography offers a potential solution to this threat, and federal agencies have been directed to begin planning for its implementation. According to Federal News Network, the need for action is urgent, and the adoption of post-quantum cryptography could be crucial in protecting sensitive data.
