  • Patent number: 11171786
    Abstract: A secure bus for pre-placement of device capabilities across a set of cryptoprocessors may be provided. A first cryptoprocessor may receive a key corresponding to a second cryptoprocessor and it may receive an object in response to the object being instantiated on the second cryptoprocessor. Next, the first cryptoprocessor may use the key to determine that the second cryptoprocessor signed the object. The first cryptoprocessor may then store the object in the first cryptoprocessor in response to determining that the second cryptoprocessor signed the object. Then the first cryptoprocessor may receive a request for the object and provide a response to the request.

  • Patent number: 6333931
    Abstract: A method and apparatus are disclosed for interconnecting a circuit-switched telephone network and a packet-switched data network for communication among them. A signaling trunk of a circuit-switched telephone network is coupled to a signaling access server that is also coupled to a signaling, management and control network. One or more voice trunks of the telephone network are coupled to one or more network access servers, which are also coupled to the control network to thereby receive instructions from the signaling access server. The network access servers are also coupled to a packet-switched data network, such as the global packet-switched network known as Internet. The signaling access server can receive call setup messages and other messages in standard telephone network protocol formats and convert them into call setup messages in a special protocol for communications between the signaling access server and the network access servers.
