Abstract
A computing system calculates a hash value of binary of a component of the computing system using a hash function and determines whether a signature that is associated with the binary of the component is valid. A trusted platform module in the computing system extends a platform configuration register value in the trusted platform module using a known value that is associated with the binary if the signature is valid.
