The wolfBoot recipes in the meta-wolfssl (https://github.com/wolfSSL/meta-wolfssl) Yocto layer can now build wolfCrypt from a wolfSSL source tree you supply. Set `WOLFBOOT_WOLFSSL_SRC = “/path/to/wolfssl”` in `local.conf` and that tree is used in place of the copy the recipe would otherwise fetch into `lib/wolfssl`. The wolfSSL entry drops out of `SRC_URI` entirely, so nothing is downloaded. […]

Introducing wolfTrust
wolfTrust is a trusted firmware platform for Arm Cortex-M, now under development at wolfSSL, that brings the full wolfSSL security stack into a single secure runtime. It implements the Arm Firmware Framework for M (FF-M) with source-compatible PSA client interfaces, so applications written for Trusted Firmware-M (TF-M) keep their psa_* calls and simply swap the […]
Read MoreMore TagComing Soon: wolfHSM Support for Infineon TRAVEO™ T2G
Automotive security is moving deeper into the silicon, and wolfSSL is continuing to expand wolfHSM support across the MCU platforms powering next-generation vehicles. Coming soon: wolfHSM support for the Infineon TRAVEO™ T2G family. Infineon’s TRAVEO™ T2G automotive microcontrollers target applications ranging from body electronics and gateways to digital clusters and other connected vehicle systems. Across […]
Read MoreMore TagwolfSSL Advances Functional Safety with ISO 26262 Documentation and ASIL-D Certification Roadmap
As automotive software continues to grow in complexity, functional safety has become just as important as cybersecurity. To help customers build safety-critical systems, wolfSSL now offers ISO 26262 documentation designed to simplify the integration of wolfSSL into products pursuing Automotive Safety Integrity Level (ASIL) certification. This documentation provides developers with the supporting materials needed to […]
Read MoreMore TagwolfSSL adds LMS and XMSS to wolfHSM
LMS and XMSS are stateful hash-based signature schemes (NIST SP 800-208) suited to long-lived firmware and code signing. wolfSSL has added support for both post-quantum cryptographic (PQC) algorithms to wolfHSM. This feature leverages the hardware security module (HSM) to securely and persistently store the “stateful” key and counter for both algorithms, as well as perform […]
Read MoreMore TagwolfHSM Now Supports the Infineon AURIX™ TC4xx
We’re excited to announce that wolfHSM now supports Infineon’s AURIX™ TC4xx. We have wolfHSM running on the TC4xx, and an initial release is coming soon. This brings wolfSSL’s portable, open-source HSM framework to Infineon’s next-generation AURIX platform, the successor to the widely deployed TC3xx family. Why AURIX TC4xx? Infineon’s AURIX™ TC4xx is the next generation […]
Read MoreMore TagwolfHSM TrustZone Now Available on STM32H5: Automotive-Grade HSM Security on a Mainstream Cortex-M33
wolfHSM on STM32H5 wolfHSM now supports the STM32H5 family. The same wolfHSM server that runs on Infineon AURIX TC3xx and ST SPC58 automotive parts now runs on a Cortex-M33, isolated by Arm TrustZone-M instead of a discrete HSM coprocessor. No extra silicon, no second MCU, no external secure element. The work is a two-part PR: […]
Read MoreMore TagwolfHSM and Concurrency
Systems that integrate an HSM often have multiple threads or subsystems performing cryptographic operations at the same time. wolfHSM is designed to support this kind of workload while keeping the request/response protocol simple and predictable. wolfHSM concurrency is primarily achieved by the server processing requests from multiple client sessions in parallel. Each session processes requests […]
Read MoreMore TagSecuring wolfHSM POSIX Transport with TLS
The recent addition of a TLS transport to the wolfHSM project provides improved transport-level protection for POSIX-based communications and was included with the latest release. Previously, when wolfHSM was used over POSIX transports (such as TCP sockets on a local system), security largely depended on controlling access to that transport. If an attacker could access […]
Read MoreMore TagBringing wolfHSM to STM32H5 TrustZone: Production-Grade HSM on a Cortex-M33
From Automotive HSM to IoT When most people hear about Hardware Security Modules, they tend to think of the automotive industry. wolfHSM has spent years proving itself on Infineon AURIX TC3xx, ST SPC58, and similar high-end automotive parts, where a dedicated HSM core stands guard over keys, signing, and secure boot inside vehicles shipping at […]
