Abstract
Methods for system component pairing and authentication are described. A first system component may pair with a second system component in response to receiving a unique identifier from the second system component. The first system component may store the received unique identifier and, thereafter, may authenticate that it is, in fact, communicating with the second system component. The first component may communicate a challenge message directed to the second system component and if the contents of the reply message and the time taken to receive the reply message do not correspond to expected values, the first component may determine that it may not be communicating with the intended second component and may cease communications with the second component.
