A device includes a receiver configured to receive a request to perform a function. A secure element connected with the receiver, the secure element to verify the request to perform the function, where the secure element is configured to operate in either a report mode or a silent mode. Details about a status of the performance of the function are displayed when the device operates in the report mode, and no details about the status of the performance of the function are displayed when the device operates in the silent mode.

System utilizing a secure element

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.

Secure electronic element network

A system monitors an application. The system includes a state table with state table nodes corresponding to application checkpoints. The state table nodes include an authorized time interval and application path. The system also includes a time counter that tracks an operation time between successive application checkpoints, and a program counter that tracks and stores an operation path for the application. A checkpoint module verifies an operation of the application at a checkpoint by comparing the authorized time interval for the checkpoint state table node and the operation time tracked by the time counter, as well as the authorized application path for the checkpoint state table node and the operation path tracked by the program counter. A security action is performed when the tracked operation time is not within the authorized time interval, or when the tracked operation path does not match the authorized application path.

System for monitoring an operation of a device

An electronic device includes a receiver configured to receive, from an entity, a request to perform a function. The electronic device also includes a secure element to verify the request to perform the function. The secure element includes hardware programmed with instructions to verify that a security of the secure element has not been breached. The secure element also includes software including instructions to determine an access right for the entity requesting performance of the function, and to perform the function when the hardware verifies that the security of the secure element has not been breached and the access right indicates that the entity is authorized to request performance of the secure function.
