Abstract: A Trojan detection system places watermark circuits within an analog circuit design that allow the system to observe a node within an analog circuit under test (CUT) that is otherwise not observable. The watermark circuit can be a pass transistor logic (PTL)-based connection between the node and a readable output pin (i.e., a “watermark output pin”). In particular, the watermark circuits can be inserted at a node where a Trojan is likely to be inserted; thus, the watermarks provide a manner for observing changes (e.g., voltage changes) caused by a malicious modification to an analog circuit. The detection system can identify potential locations (nodes) in the CUT where a Trojan may be inserted using one or more neural networks. The detection system can then insert watermark circuits connected to the identified locations.

Abstract: The present disclosure is directed to systems and methods enabling federated learning of atmospheric models for satellite-based navigation, via crowdsourcing training data. One method includes, causing, at a computing device, a determination of an error metric based on a difference between a set of measured values and a set of expected values. The set of expected values is based on an atmospheric model and a geolocation. The set of measured values is based on a set of satellite signals received at the computing device from a set of satellites. The error metric may be for the atmospheric model. The method further includes causing a transmission of a data structure from the computing device to an atmospheric model service. The transmitted data structure encodes the error metric (e.g., training data). The atmospheric modeling service employs Bayesian inference and the error metric as a conditional probability to refine the atmospheric model.
