Quantum Computing Threat Demands Immediate Cryptographic Transition Planning

The emergence of quantum computing poses an existential threat to current cryptographic standards, with adversaries already collecting encrypted data through 'harvest now, decrypt later' attacks. Organizations face a massive coordination challenge to transition trillions of dollars in secured value to post-quantum cryptography before quantum computers become capable of breaking current encryption. The slow adoption of post-quantum standards and potential breakdown of digital signatures could enable widespread impersonation attacks and compromise the entire foundation of digital security.
