    摘要： A device includes a key store memory, a rule set memory, a plurality of cryptographic clients, and a key store arbitration module. The key store memory stores a plurality of cryptographic keys and the rule set memory stores a set of rules for accessing the cryptographic keys. A cryptographic client is operable to issue a request to access a cryptographic key(s) and, when access to the cryptographic key is granted, execute a cryptographic function regarding at least a portion of the cryptographic key to produce a cryptographic result. The key store arbitration module is operable to determine whether the request to access the cryptographic key is valid; when the request is valid, interpret the request to produce an interpreted request; access the rule set memory based on the interpreted request to retrieve a rule of the set of rules; and grant access to the cryptographic key in accordance with the rule.

    摘要： A processing system includes a memory module that includes a plurality of memory blocks and a plurality of registers. A processor executes an operating system having a plurality of operating system processes, wherein each of the plurality of operating system processes is designated as a corresponding one of a plurality of virtual clients. A memory arbitration module receives a request to access a selected one of the plurality of memory blocks or registers from at least one of the plurality of virtual clients and determines whether or not to grant or deny the request, based on whether the selected memory block or register is designated for trusted or untrusted access and based on whether the virtual client is trusted or untrusted.

    摘要： A processing system includes a memory module that includes a register space for storing a plurality of register data in a plurality of registers and secure access data corresponding to the register space. A register arbitration module operates to receive a request to access one of the registers from a client module; retrieve secure access data corresponding to the client to determine if the client is trusted; and to grant the request to access the register if the client is trusted. If the client is not trusted, the register arbitration module retrieves secure access data to determine if the register is non-secured for the client. The register arbitration module grants the request to access the register when the register is non-secured for the client.

    摘要： A content access device includes an interface module having a plurality of interfaces that operate in accordance with a corresponding plurality of interface formats. The interface module is programmable to select at least one of the plurality of interfaces to receive a transport stream and output a processed transport stream. The interface formats include a plurality of broadcast video card formats and a plurality of wired computer interface formats. A key storage device stores at least one key. An encryption processing device retrieves the at least one key from the key storage device, and then processes the transport stream based on the at least one key to generate the processed transport stream.
