News to look forward to—wolfSSL plans to integrate wolfTPM, our portable TPM 2.0 library, into U-Boot! This would extend the TPM 2.0 capabilities in U-Boot to include signature verification and measured boot.

For many platforms, we can replace U-Boot such as on the Xilinx UltraScale+ MPSoC.

wolfBoot is a portable secure bootloader solution that offers firmware authentication and firmware update mechanisms. Thanks to its minimalistic design, wolfBoot is completely independent from any OS or bare-metal application. Some of its key features include:

Partition signature verification using ED25519, RSA and ECC Encryption of partitions Updating of partitions in the boot loader Measured boot with TPM 2.0 PCR registers Offloading to crypto coprocessors like the TPM 2.0 modules Version checking for updates Rollback on failed updates
