Abstract
Embodiments of information processing systems and associated components can include logic operable to perform operations in a virtualized system including a plurality of guest operating systems using descriptors. The descriptors specify a set of commands defining the operations in a plurality of security domains and specify permission to a plurality of resources selectively for the plurality of guest operating systems.
Claims20
An electronic circuit comprising:
- a module configured to perform operations specified by a descriptor comprising a set of commands that define the operations, a digital signature that verifies validity of the descriptor, and a security domain identifier that specifies access to resources in a plurality of security domains.
An information processing system comprising:
- logic operable to perform operations in a virtualized system including a plurality of guest operating systems using descriptors that specify a set of commands defining the operations in a plurality of security domains and that specify permission to a plurality of resources selectively for the plurality of guest operating systems.
A method for securing an information system comprising:
- performing operations in a system including a plurality of entities;
- controlling the performance of operations using a plurality of descriptors;
- specifying in ones of the plurality of descriptors a set of commands defining the operations in a plurality of security domains;
- and
- specifying in ones of the plurality of descriptors permission to a plurality of resources selectively for the plurality of entities.
