"Patient adversaries are employing a "Harvest Now, Decrypt Later" (HNDL) strategy. They are quietly accumulating encrypted data with the intention of decrypting it later using quantum computers. Any data requiring long-term security, such as trade secrets or classified designs, is vulnerable because its lifespan will inevitably outlive its current encryption."
"Harnessing quantum physics, future quantum machines will effortlessly break the mathematical encryption schemes that protect data today. Current prototypes are not quite there yet because they fundamentally lack the scale and error-correction capability required to successfully execute complex quantum algorithms. However, the prospect of a mature, cryptographically relevant quantum computer (CRQC) is alarming."
"To combat the looming quantum computing threat, our cryptography must evolve immediately. This is why Post-Quantum Cryptography (PQC) is being introduced as a solution. PQC provides new cryptographic algorithms designed to withstand quantum decryption attacks."
Criminals employ a "Harvest Now, Decrypt Later" strategy, accumulating encrypted data for future decryption using quantum computers. Digital evolution and cloud storage enable large-scale data theft. Current encryption schemes face vulnerability because data lifespans exceed encryption durability. Quantum computers, expected by 2030-2035, could break modern encryption in minutes. Post-Quantum Cryptography (PQC) offers new algorithms designed to resist quantum decryption. Organizations must begin PQC migration planning immediately to ensure data encrypted today remains secure against future quantum-enabled attacks, particularly for trade secrets and classified designs requiring long-term protection.
