A major release for wolfTPM came out at the end of 2020 and is now available for download from our website. This release brings many new features:
- Native support for using TPM2.0 hardware with wolfTPM under Microsoft Windows
- TPM simulator support for even easier development with wolfTPM and MacOS users
- Protection from MITM (man-in-the-middle) attacks using TPM2.0 Parameter Encryption. wolfTPM supports both TPM2.0 options for MITM protection, XOR encryption and AES CFB.
- HMAC Session support for verification of peer authenticity and integrity.
This release also adds multiple new examples: TPM key generation and key loading examples with options to store the key to disk and use parameter encryption to protect from MITM. Added is support for importing external private keys and easy re-loading. And for those who use the internal TPM clock for reference, there is now a TPM clock increment example.
Among the other enhancements of our portable TPM2.0 library are the use of HMAC sessions and new wolfTPM wrappers for easier work with TPM sessions and authorization of TPM objects.
