U-Boot with wolfTPM Update

News to look forward towolfSSL 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
