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.
