ABSTRACT:
An integrity signature may provide information about a platform used to create a digital signature. The value of a digital signature may be related to the integrity and trustworthiness of the platform on which it is created. Signed platform integrity information provides a measure of trust regarding the platform used to create the digital signature. The integrity signature may be created separately from a document signature, or a combined integrity and document signature may be provided.
