wolfBoot Secure Boot for the Nordic nRF54L15 and nRF54LM20
wolfBoot now supports the Nordic nRF54L15 and nRF54LM20 wireless SoCs on the nRF54L15 DK and nRF54LM20 DK boards. The nRF54L15 has been supported since wolfBoot 2.8.0, and the nRF54LM20 is available in PR#930. wolfBoot verifies signed firmware before it runs and every update before it is installed, with optional TrustZone isolation between the bootloader and […]

Read MoreMore TagLIVE WEBINAR: The wolfCrypt Linux Kernel Module: Post-Quantum, Self-Healing, Faster Than Ever
Your current Linux kernel may lack newer cryptographic algorithms and encryption acceleration—even when your hardware supports it. Upgrading the kernel isn’t always practical. Join wolfSSL to explore how the wolfCrypt Linux kernel module brings post-quantum cryptography and accelerated encryption to existing Linux deployments. Learn how it also detects VM cloning and snapshot restores and automatically […]
Read MoreMore TagwolfBoot Replaces the FSBL on AMD Zynq UltraScale+ MPSoC
wolfBoot can now be the first stage boot loader (FSBL) on the AMD Zynq UltraScale+ MPSoC. The BootROM authenticates wolfBoot into the 256 KB OCM and enters it at EL3. wolfBoot brings up the processing system (PLLs, DDR, MIO, clocks) and boots Linux from a wolfBoot-signed FIT. Validated end to end on a ZCU102 to […]
Read MoreMore TagLIVE WEBINAR: Quantum-Ready Avionics: Embedded DTLS and Secure Boot for the Next 30 Years
Aircraft remain in service for decades, but cryptographic standards continue to evolve. Some security decisions are easy to update later. Others aren’t. Join us to Learn how embedded DTLS, secure boot, hardware root of trust, and post-quantum cryptography fit together to build avionics platforms that can adapt over a 30-year lifecycle. In this webinar, you’ll […]
Read MoreMore TagReducing Yocto and OpenWRT RAM Usage by Switching from OpenSSL to wolfSSL
On Yocto Linux Scarthgap, the wolfSSL endpoint process peaks at 10–13 KB of heap + stack, compared with 750–790 KB for OpenSSL, for an ECDHE P-256 / ECDSA P-256 / AES-128-GCM connection. These figures apply in both directions and to both TLS 1.2 and TLS 1.3. On OpenWRT using uclient-fetch to grab 100k of data, […]
Read MoreMore TagSecure Boot for the Raspberry Pi Compute Module 4 with wolfBoot and FIPS 140-3
The Raspberry Pi Compute Module 4 (CM4) is a popular choice for industrial edge devices, but out of the box nothing enforces a hardware-rooted chain of trust over the OS it boots. wolfBoot now targets the CM4 (Broadcom BCM2711, quad-core Cortex-A72), replacing U-Boot with a verified boot chain rooted in your own keys. How It […]
