Pseudo Random Number Generator (PRNG) Software-generated random numbers only are pseudorandom. They are not truly random because the computer uses an algorithm based on a distribution, and are not secure because they rely on deterministic, predictable algorithms. Since a seed number can be set to replicate the “random” numbers generated, it is possible to predict […]

We are adding hardware security to wolfSSH to meet the rising security requirements for connected systems. Thanks to the widely available Trusted Platform Module (TPM) and our portable wolfTPM library, wolfSSH can have the user’s private SSH key stored and used directly from a hardware security module. This way the private key material is never […]

We are integrating wolfTPM into U-Boot. This will 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. Our wolfBoot allows many features including: * Partition signature verification using ED25519, RSA and ECC * Encryption of partitions […]
