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, […]

Getting the Best Open Source Support from wolfSSL
At wolfSSL, we love supporting the open source community. Our roots are in open source, and many of the projects that rely on wolfSSL, wolfCrypt, wolfSSH, wolfBoot, wolfTPM, and our other libraries are open source themselves. Whether you are integrating wolfSSL into a hobby project, contributing to a larger ecosystem, building a product on top […]

The AMD Versal™ Gen 1 VMK180 evaluation kit integrates Arm® Cortex®-A72 processors with programmable logic and AI engines in a single device. This article announces wolfBoot support on the VMK180, showing how a vendor-neutral secure bootloader can provide cryptographically verified boot and secure, updatable firmware for Versal-based systems. wolfBoot Features wolfBoot is a vendor-neutral, portable […]
Read MoreMore TagAccelerating ML-DSA Key Generation with wolfSSL and CUDA
With the formalization of ML-DSA for post-quantum usage, lattice-based cryptography introduces a significant compute challenge. Unlike traditional ECC or RSA, ML-DSA relies on complex polynomial math across hundreds of dimensions, creating a performance wall for high-volume systems. To address this compute issue, wolfSSL can utilize CUDA to accelerate these lattice operations, offloading the heavy math […]
