The quantum threat isn't hypothetical, it's operational. Adversaries are already harvesting encrypted defense traffic today, banking on decrypting it once a cryptographically relevant quantum computer exists. For the military's forward-deployed edge, that traffic includes command and control, intelligence, and mission data meant to stay secure for decades.
The Department of War's Post-Quantum Cryptography Strategy requires all systems to support quantum-resistant algorithms by 2030 and operate on them by 2031. CNSA 2.0 requires every new National Security System acquisition to be compliant by January 2027.
The direction is clear; execution is not. Most operational cryptography has never been fully inventoried, and the tactical edge, constrained devices, legacy links, denied and degraded environments, is where migration is most likely to stall.
Swapping algorithms won't close this gap. It takes crypto-agility built into the infrastructure, a migration sequence that survives contested conditions, and hard calls on the systems that can't wait until 2031.
Join GIST360’s latest breakfast briefing installment which will convene senior Defense and Military leaders for a candid working session before Day 2 of AUSA on the strategies, tradeoffs, and hard decisions ahead.
