Building a practical path to post-quantum cryptography

Quantum computing presents both potential and threat to current digital security. While it may eventually break existing encryption, the transition to quantum-resistant algorithms is a manageable evolution rather than an abrupt crisis. Trusted technology partners like Intel are beginning to offer the necessary infrastructure for this transition.

A recent survey of quantum computing experts revealed a 50-50 probability of a quantum computer cracking a 2048-bit RSA key within 24 hours by 2040, suggesting that businesses have time to plan. The near-term focus should be on collecting encrypted data now, with plans to decrypt later when the capability exists.

The U.S. government is signaling confidence in post-quantum cryptography (PQC), requiring new National Security Systems to support Commercial National Security Algorithm Suite 2.0 (CNSA 2.0) in January 2027, with 100% adoption targeted by 2035. While these timelines are not mandates for commercial enterprises, they can serve as reference points for planning.

Intel is actively delivering quantum-resistant capabilities across its product portfolio, including memory encryption, firmware and software signing, device interconnects, and secure boot functions. The company's quantum-safe memory encryption and optimized libraries for post-quantum algorithms help reduce latency and preserve service-level agreements.

A practical roadmap for enterprises involves viewing PQC as modernization, leveraging trusted partners like Intel, evaluating platform readiness, starting with visibility into cryptographic assets, and adopting a phased approach that mirrors trends in government and critical infrastructure sectors.
