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. That’s where DICE (Device Identifier Composition Engine) comes in. DICE composes a device identity […]

As cryptographic standards and regulatory requirements continue to evolve, the ability to adopt modern security protocols without sacrificing compliance is increasingly important. TLS 1.3 plays a critical role in this evolution — not only as today’s baseline for secure communications but also as the foundation for the ongoing transition toward Post-Quantum Cryptography (PQC). With recent […]

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, and standard interfaces over complex […]
Read MoreMore TagwolfSSL 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. Edmonds, Washington – April 7, 2026 – wolfSSL Inc. today announced wolfIP, […]

Satellites, rockets, and ground stations face unique cybersecurity challenges, from communication interception to firmware tampering. Protecting these systems requires lightweight, space-grade cryptography designed for long lifecycles and constrained embedded environments. Register now: Designing Secure Satellite Systems with FIPS 140-3, CNSA 2.0, and PQCDate: April 8 | 9 AM PT These challenges directly impact system design, […]
Read MoreMore TagwolfTPM: Hardware SPI and TPM 2.0 Firmware Update Support for U-Boot
Secure boot architectures require more than just the presence of a TPM; they require a high-performance communication interface and a mechanism for lifecycle management. wolfSSL has updated wolfTPM and U-Boot to support native Hardware SPI communication and direct TPM 2.0 firmware updates for the Raspberry Pi 4. These changes move away from generic software-based implementations, […]
