| title: SPI-attached Trusted Platform Module conforming to TCG TIS specification |
| - Lukas Wunner <lukas@wunner.de> |
| The Trusted Computing Group (TCG) has defined a multi-vendor standard |
| for accessing a TPM chip. It can be transported over various buses, |
| one of them being SPI. The standard is named: |
| TCG PC Client Specific TPM Interface Specification (TIS) |
