Abstract
An integrity verification process is performed by an integrity verification module of a client computing device. When the computing device is powered-up, but before an operating system is booted, the integrity verification module performs an integrity check of the computing device and gathers integrity verification information to ensure that the system is secure. If the system passes the integrity check, the system boots to a browser session which is capable of communicating with a cryptographic module. In response to a request from a service provider, the computing device retrieves the integrity verification information and signs the integrity verification information using a private key from the cryptographic module and forwards the signed data to the service provider. The integrity of the computing device may then be verified using a known public key of the cryptographic module that is accessible from a trusted third party.
