Examples of the present disclosure describe systems and methods for implementing a cloud-based private area network. In aspects, various customer devices may be connected to a cloud-based carrier or wireless carrier. The carrier may use identification information associated with each customer device to group devices by, for example, customer account. For each customer account, the carrier may create and/or assign a customer-specific gateway. The customer gateway may enable devices identified as associated with an account to detect and communicate securely with each other over a cloud-based private area network. Additionally, each customer gateway may provide several functions typically found in private or home gateways and local area networks (LANs) to the devices associated with an account.

Cloud-based private area network

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.

USB interface for performing transport I/O

The present disclosure relates to systems and methods for assembling and extracting command and control data. In embodiments of the present disclosure, the command and control data is segmented and inserted into multiple packet headers. The header packets are identified by flags such as 'First portion,' 'Middle portion,' &#x201c;Last portion,&#x201d; or &#x201c;Null Byte.&#x201d; When a receiver extracts the command and control data from the headers, it tracks the flags associated with the headers. The command and control data is saved to buffer in association with its associated flag. The receiver uses the flags to determine when all command and control data headers have been received. The command and control data is then reconstructed and used to decrypt audio visual content.

Systems and methods for assembling and extracting command and control data

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.
