1. A method of determining a signature of an identifier of a computing device, comprising the acts of:

  • receiving the identifier at a port;

    storing the identifier in a first computer readable storage medium coupled to the port;

    providing a value;

    at a processor coupled to the first computer readable memory, applying a hash function to a combination of the identifier and the value, thereby generating a hash value;

    applying a cryptographic process which is secure in an untrusted computing environment to the hash value;

    combining a result of the cryptographic process and the value thereby, to define a signature; and

    storing the signature in a second computer readable medium which is coupled to the processor.
