    摘要： Various embodiments described herein relate to apparatus for executing software in a secure computing environment. A secure processor can be used and configured to request a context swap from a first context to a second context when switching execution from a first portion of software to a second portion of software. A context manager, which can be in communication with the secure processor, can be configured to receive and initiate a requested context swap. A trust vector verifier, which can be in communication with the secure processor and the context manager, can be configured to load a trust vector descriptor upon command from a context manager.

    摘要： Systems and methods for implementing a Transport I/O system are described. Network encrypted content may be received by a device. The device may provide the network encrypted content to a secure processor, such as, for example, a smart card. The secure processor obtains a network control work that may be used to decrypt the network encrypted content. The secure processor may decrypt the network encrypted content to produce clear content. In embodiments, the secure processor may then use a local control word to generate locally encrypted content specific to the device. The device may then receive the locally encrypted content from the secure processor and proceed to decrypt the locally encrypted content using a shared local encryption key. The transport I/O system ensures the protection of the network control word by maintaining the network control word on the secure processor.
