Abstract
A secure network of electronic elements (“network”) ensures the electronic elements that implement an electronic device are functioning properly. The network selects at least one master electronic element to consistently check that each of the electronic elements are functioning properly. When the master electronic element identifies that an electronic element is not functioning properly, the network executes a predefined response, such as a counter measure that limits the functional capability of the improperly functioning electronic element or other electronic elements. Electronic elements can identify when a master electronic element is improperly functioning by observing that the master electronic element has ceased checking on the electronic elements. The secure network can then execute a response that includes the counter measure of limiting the functional capability of the improperly functioning master electronic element and assigning a new master electronic element.
