wolfTPM is a TPM 2.0 project, designed for embedded use. It is highly portable, due to having been written in native C, having a single IO callback for SPI hardware interface, no external dependencies, and its compacted code with low resource usage.
It is generally very easy to compile on new platforms, so if your desired platform is not listed as supported or you would like assistance porting wolfTPM, please contact wolfSSL at email@example.com.
*Provides all TPM 2.0 API's in compliance with the specification.
*Uses the TPM Interface Specification (TIS) to communicate over SPI.
*Includes wrappers for Key Generation, RSA encrypt/decrypt, ECC sign/verify, ECDH, NV Access and Hashing.
Functional blocks of a TPM
The TPM supports key and lifecycle management with its unique endorsement key and key hierarchies. The non-volatile memory can be used to securely store sensitive data like certificates. It is based on tamper-resistant hardware with more than 50 security features including sensors and memory encryption capabilities for hardened protection of secrets. The TPM also features a secure tick counter for a trusted time source.
