Replacing TF-M on ARMv8-M: wolfBoot Secure Domain & wolfPSA, now integrated with Zephyr for CRA compliance

ARMv8-M TrustZone (TrustZone-M) gives Cortex-M23, Cortex-M33, Cortex-M35P and related MCUs a clean, hardware-enforced way to split a system into two execution environments: Secure world: the hardware root of trust, key material, security services, and the code that configures isolation. Non-secure world: the main RTOS and application logic, kept away from secrets by hardware boundaries. In […]

wolfSSH Memory Size Reduction

Reducing wolfSSH Footprint: Logging Optimization and Other Size-Saving Options Embedded and resource-constrained systems often demand tight control over code size, memory usage, and runtime overhead. A recent improvement to wolfSSH directly addresses this need by reducing logging overhead when debugging is disabled. Eliminating Logging Overhead with a No-Op WLOG Historically, even when debugging was disabled, […]

wolfSSL and OpenTitan: Securing the Open Silicon Era

wolfSSL is initiating support for OpenTitan, the open-source silicon Root of Trust. Our implementation will integrate with OpenTitan’s hardware accelerators, specifically the OpenTitan Big Number (OTBN) unit, AES, and HMAC/KMAC blocks, to offload cryptographic operations from the host RISC-V core. This integration provides a transparent, FIPS-ready security stack for embedded designs. The programmable OTBN unit […]

NXP S32K1 CSE Hardware Acceleration supported by wolfSSL

wolfSSL now supports using the Cryptographic Services Engine (CSE) on NXP S32K1 microcontrollers for hardware-accelerated cryptography. The CSE is a secure coprocessor integrated into automotive-grade microcontrollers like the S32K148, providing AES acceleration, hardware TRNG, and secure key storage. The port uses wolfSSL’s Crypto Callback mechanism, so when operations aren’t supported by CSE hardware (like AES-192/256), […]
