Revisiting the TPM

TPMs have been shipping for nearly 8 years now.  WinMagic was an early adopter and supported TPM version 1.1 for full disk encryption before most.  We expanded our support to the more main stream version 1.2 TPMs when they started shipping.  Now more than 100 Million TPMs are out there in laptops and other devices, and soon many, many  Version 2.0 TPMs will join them.  TPM 2.0 and disk encryption will be a good topic for a future blog but today I am going to set the ground work on where we are today.
