SECURING STORED CONTENT FOR TRUSTED HOSTS AND SAFE COMPUTING ENVIRONMENTS

摘要

Techniques for protecting content to ensure its use in a trusted environment are disclosed. The stored content is protected against harmful and/or defective host (or hosted) environments. A trusted security component provided for a device can verify the internal integrity of the stored content and the host before it allows the content to come in contact with the host. As a counter part, a trusted security component provided for the host can verify and attest to the integrity of the host and/or specific host computing environment that can be provided for the content stored in the device. The trusted security component provided for a device effectively verify the host integrity based on the information attested to by the trusted security component provided for the host. If the trusted security component trusts the host, it allows the trusted host to provide a trusted host computing environment trusted to be safe for the content stored in the device. A trusted host can effectively provide a safe virtual environment that allows a content representing a copy (or image) of an original computing environment to operate on the host computing system to give a similar appearance as the original computing environment.
