Post-Quantum Cryptography: What’s Next for Edge Security

Rich Salz is a Principal Architect in Architecture & Technology Strategy at Akamai. He has been involved in the definition and implementation of internet and security standards for more than 30 years, actively with the IETF and the QuicTLS toolkit. At Akamai, he works on making systems and customers more secure by default.

Key takeaways

While ML-DSA remains the primary general-purpose standard, newer post-quantum signatures like FN-DSA (Falcon) offer smaller footprints but introduce complex floating-point implementation challenges.

Major industry players are accelerating transition timelines to 2029, a shift Akamai is matching by preparing to offer post-quantum cryptography (PQC) certificates by that same year.

Prominent cryptographers agree that symmetric encryption remains highly secure, meaning quantum computers do not threaten AES-128 or require a transition to 256-bit keys.

The newly chartered PLANTS working group at the…
