Quick Take
NIST has finalized Special Publication 800-232, standardizing the Ascon family of algorithms to secure resource-constrained devices such as sensors, RFID tags, and medical implants. CIOs should direct procurement teams to prioritize IoT products with Ascon support on their roadmaps, ensuring vetted security without draining batteries or budgets.
Why You Should Care
The Internet of Things is scaling fast across industries, from logistics and manufacturing to healthcare and smart cities. Yet many of these devices ship with underpowered processors and tiny batteries, meaning they often rely on weak or outdated security. That gap has left enterprises juggling the benefits of IoT with the risk of breaches through “the weakest link” endpoints.
With Ascon now standardized by NIST, vendors have a clear and vetted way to secure data on constrained devices without compromising performance. For CIOs, this translates into reduced risk of data leakage from medical devices, RFID systems, or embedded sensors. It also creates a compliance baseline that makes it easier to compare vendors, especially in regulated industries like healthcare and finance.
Equally important, the standard arrives at a time when attackers are increasingly probing IoT environments for easy entry. Aligning with Ascon shows regulators, partners, and customers that your organization is not leaving IoT endpoints unguarded.
What You Should Do Next
- Direct procurement and vendor management teams to request vendor roadmaps on Ascon adoption.
- Align device refresh cycles with expected Ascon-enabled hardware and firmware updates.
- Treat pilot deployments as a low-cost way to evaluate performance and ensure compatibility with existing systems.
Get Started
- Review contracts for upcoming IoT device purchases and add language preferring Ascon-compliant security.
- Work with vendors to confirm timelines for firmware and hardware updates that incorporate the standard.
- Brief the board and regulators that the enterprise is aligning with NIST’s latest recommendations, reinforcing your risk posture.
- Plan for future standards by ensuring teams are flexible enough to swap in updated cryptography as the ecosystem evolves.
