Intel's PQC roadmap: quantum-safe crypto is a manageable evolution, not a crisis

Quantum computing's threat to encryption has been framed as either catastrophe or irrelevance, but Intel's sponsored analysis positions PQC as a deliberate evolution. A Global Risk Institute survey of 32 experts places a 50-50 probability of breaking 2048-bit RSA keys within 24 hours by 2040. The near-term concern is 'harvest now, decrypt later' attacks, where adversaries archive encrypted data today for future decryption—especially for information needing confidentiality beyond 10 years. That timeline allows structured modernization, not panic.

Government signals offer a blueprint: U.S. National Security Systems must support NIST-standardized CNSA 2.0 algorithms by 2027, with full adoption by 2035. Intel is already shipping foundational tech—the Xeon 6 processor includes quantum-safe AES-256 memory encryption and microcode signing. Future platforms will expand post-quantum algorithms to firmware signing, device interconnects, attestations, and secure boot, while Intel QuickAssist Technology offloads cryptographic workloads to minimize performance hits from larger PQC key sizes. This gives enterprises a phased path to compliance and resilience.
