Abstract
The present invention relates to trust in computing platforms and the like. In particular, embodiments of the invention provide a trusted computing entity (64), providing an environment comprising one or more of a set or sets of available security algorithms (62), the entity (64) being adapted to operate on data (702), which data has associated security criteria (704), only if the environment meets the associated security criteria.
Claims25
A trusted computing entity for carrying out security operations on data items each of which is associated with a respective trusted operating environment that is characterised by one or more security algorithms or sets of security algorithms trusted for operating on data items, the trusted computing entity having an operating environment that is characterised by one or more security algorithms or sets of security algorithms for operating on data items, and the entity being adapted to operate on a said data item only if the operating environment provided by the entity is compatible with the trusted operating environment of the data item.
A method of processing an item of data in an operating environment, the item of data having associated with it a trusted operating environment that is characterised by one or more security algorithms or sets of security algorithms trusted for operating on data items and the operating environment being characterised by one or more security algorithms or sets of security algorithms, the method including operating on the data item only if the operating environment is compatible with the trusted operating environment of the data item.
