wolfSSL runs the full set of NIST post-quantum algorithms on the STM32C5. Below are the measurements on a NUCLEO-C5A3ZG with a Cortex-M33 at 144 MHz. ML-KEM (FIPS 203) key exchange. ML-KEM-768 encapsulates in 5.9 ms and decapsulates in 7.7 ms. ML-DSA (FIPS 204) signatures at all three parameter sets. ML-DSA-44 verifies in 18.5 ms. LMS/HSS […]

Trimming wolfCrypt to PQC for DO-178
From January 1, 2027, all new National Security Systems acquisitions must be CNSA 2.0 compliant by default, and software and firmware signing must be CNSA 2.0 exclusively by 2030. Military avionics is NSS. Are you ready? Airframes then run 30 to 50 years. A DAL A root of trust certified on RSA-2048 today outlives every […]
Read MoreMore TagwolfHSM ML-DSA Optimization: External-Mu
Here at wolfSSL we never leave an optimization on the table in any of our products. We are currently working on a new optimization known as External-Mu in the PKI community. In ML-DSA, you sign a message directly; no pre-hash which is similar to Ed25519 and Ed448 but different from ECDSA. But the very first […]
Read MoreMore Tagwc_MlDsaKey_Sign() Versus wc_MlDsaKey_SignCtx()
If you have been looking around wolfcrypt’s APIs and source code you might have noticed that both wc_MlDsaKey_Sign() and wc_MlDsaKey_SignCtx() exist and you might wonder about the difference. TL;DR wc_MlDsaKey_SignCtx() differs from wc_MlDsaKey_Sign() in that it adds a 1 byte marker (0x00), a length specifier for the context string, and a context string. If you’re […]
Read MoreMore TagPost-Quantum Cryptography Is Coming to the wolfSSL Ada Wrapper
Ada is the language of systems that stay in service for decades — avionics, rail signalling, spacecraft, defense platforms. That lifetime is the problem. This makes you susceptible to “Trust now, Forge Later” type attacks if you aren’t building in agility into your software maintenance practices. The wolfSSL Ada/SPARK binding, available in the main wolfSSL […]
Read MoreMore TagwolfSSL at the Toradex Booth: Post-Quantum the SMARC iMX95 SoM
Heading to Embedded World North America (September 22–24)? Stop by Toradex at Booth 6222 to see wolfSSL’s live Post-Quantum Cryptography (PQC) demo on the Toradex SMARC iMX95 module. Afterward, visit the wolfSSL booth (#6027) to say hi and talk with our team. The Demo at a Glance We demonstrate post-quantum security across both halves of […]
Read MoreMore TagPost-Quantum Secure Boot on the NXP i.MX95 Cortex-M7
We ported wolfBoot to the Cortex-M7 on NXP’s i.MX95, running on a Toradex SMARC iMX95 module, and measured ML-DSA-87 verified boot with the core at 800 MHz. Verification and boot completed in 5.25 ms, and the ML-DSA-87 build of wolfBoot came out 940 bytes smaller than the ECDSA P-256 build of the same target. Algorithm […]
Read MoreMore TagPost-Quantum Benchmarks on the NXP i.MX95 and Toradex SMARC
We benchmarked wolfSSL’s post-quantum algorithms against OpenSSL on a Toradex SMARC iMX95 Hexa 8GB module running Torizon OS 7.7.0. Both stacks ran on the same silicon, one Cortex-A55 core, governor pinned at 1800 MHz, one second per measurement. Torizon ships OpenSSL 3.5.7, which has native ML-KEM and ML-DSA, so this compares two builds you can […]
Read MoreMore TagPost-Quantum TLS at the Edge: wolfSSL on NVIDIA Jetson Orin
The NVIDIA Jetson Orin Nano is widely deployed in robotics, industrial vision and edge AI, where devices terminate TLS, verify signed firmware, and are increasingly expected to have a post-quantum migration path. Whether that migration is affordable on embedded silicon is a practical question, so we measured it: what the Orin Nano’s CPU delivers for […]
