A method in one embodiment creates a model of an authentic IC for use in comparisons with counterfeit ICs. The model can be created by determining a first or initial set of points of interest (POIs) on the simulated physical (e.g., gate level) layout and simulating side channel leakage from each POI and then expanding the size of the POI and repeating the simulation and comparing successive simulation results (between successive sizes of POIs for a given POI) to determine if a solution for the size of the POI has converged. The final POIs are then processed in a simulation that can use multiple payloads (e.g., cryptographic data) over the entire set of final POIs, and the resulting data set can be used to create the model.

Adaptive leakage impact region detection and modeling for counterfeit chips detection

Methods, machine readable media and systems for evaluating, through one or more simulations, the leakage of sensitive data in an integrated circuit, such as cryptographic data or keys, are described. The embodiments can use machine learning models, such as one or more neural networks to generate one or more leakage related scores for each portion in a set of portions of the cryptographic data. In one embodiment, leakage data associated the first set of POIs with one or more neural networks is processed by the one or more neural networks to identify the POIs that leak the most and determine one or more scores for each portion in the set of portions of the cryptographic data.

Machine learning for automatic identification of points of interest for side channel leakage

Provided are a network operation support system and a network device management method, belonging to the technical field of communications. The system uses a micro-service architecture realized based on a container, and the system itself has a good expansibility and availability, and supports automation and layout in a cloud environment. In addition, the system also uses a main database to synchronously store operating data of various micro-services for unified maintenance of the data, thereby improving the analysis efficiency of the system.
