Abstract
Methods and systems for detection and prevention of exploitation of embedded devices. A sensing component is configured to detect a plurality of emanated analog signals and generate one or more synchronization events. The synchronization events are used to perform one or more attestation analyzes, including execution attestation, integrity attestation, and control-flow reconstruction, the results of which may be used to generate security events.
Claims18
A system, comprising:
- a sensing component configured to detect a plurality of analog emanations from one or more components of an embedded device, an analog emanation comprising an analog signal associated with execution of a function of the embedded device;
- a synchronization event generator configured to generate one or more synchronization events based on one or more analog emanations detected by the sensing component, a synchronization event identifies one or more functions of the embedded device associated with the one or more analog emanations detected;
- an event analysis and state estimation component configured to analyze one or more synchronization events generated by the synchronization event generator;
- and generate one or more attestation determinations;
- and
- a security event generator configured to generate one or more security events based on one or more attestation determinations outputted by the event analysis and state estimation component.

A method of security protection of embedded devices, comprising:
- detecting, by one or more sensors of a monitoring system, one or more analog emanations of an operating embedded device, an analog emanation comprising an analog signal associated with execution of a function of the operating embedded device;
- generating one or more synchronization events by a synchronization event generator, a synchronization event identifies one or more functions of the operating embedded device associated with the one or more analog emanations detected;
- identifying one or more attestation determinations based on the one or more synchronization events;
- and
- generating one or more security events based on the one or more attestation determinations.
