Abstract
A Trusted Activation License (TAL) can be comprised of a key unique to a Trusted Platform Module (TPM) and identifying information of the software applications bundled with the computing device having that TPM. To activate the software applications, the identifying information in the TAL can be compared against that of the software applications being activated, and the unique TPM key in the TAL can be compared against that of the TPM on the computing device on which the activation is taking place. Subsequent validations can be based on a protected association between the TAL and an Attestation Identity Key (AIK) that can be generated by the TPM as part of the activation step. Optionally, Platform Configuration Registers (PCRs) of the TPM can be periodically changed during validation to protect against useage of one TPM for validations on multiple computing devices.
