  wolfBoot adds DICE and Measured boot via PSA Initial Attestation

  Secure boot establishes authenticity (“this image is signed by a trusted key”). But many modern deployments also need attestation: a portable, verifiable way to prove what actually booted to a relying party: during onboarding, after updates, and throughout a device’s lifetime.

  Introducing wolfIP: a tiny, safe TCP/IP stack for embedded and safety critical systems

  If you have ever tried to drop a full networking stack into a deeply embedded target, you know the drill: memory budgets get tight, timing gets unpredictable, and dynamic allocation can turn certification efforts into a slog. wolfIP is our answer: a compact TCP/IP stack that favors determinism over surprise,...

  wolfSSL Inc. Announces wolfIP, a Tiny, Deterministic TCP/IP Stack for Embedded and Safety-Critical Systems

  wolfIP is a deterministic TCP/IP stack designed for embedded and safety-critical systems where memory usage, timing, and behavior must be defined before runtime. By eliminating dynamic allocation and fixing system resources up front, it enables predictable operation that supports verification and certification efforts.
