In one embodiment, a method can include the following operations: splitting the model of the IC into a plurality of tiles; simulating the IC with an elevated temperature of each tile to predetermined level; computing a temperature-dependent leakage power for each tile; and identifying a tile of the IC as including a Trojan component based on the temperature-dependent leakage power computed.

Abstract: Methods, machine readable media and systems for near-field electromagnetic simulation for side-channel emission analysis of an integrated circuit (IC) are described. In one embodiment, a method can include the following operations: simulating EM field strengths for a plurality of grid partitions of a circuit area of the IC based on a cryptographic work load applied to a model of the IC; identifying one or more of the grid partitions as a security sensitive region for the IC based on the EM field strengths, wherein one or more grid partitions outside of the security sensitive region are identified as non-security sensitive regions for the IC; and simulating EM fields for the IC to perform the EM side-channel emission analysis, wherein contributions of the EM fields from the non-security sensitive regions for the EM side-channel emission analysis are based on a linear superposition of wire currents in the non-security sensitive regions of the IC.

Abstract: 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.

Abstract: A magnetically reconfigurable robot joint motor includes a coil stator, a permanent magnet rotor and a magnetic reconfiguration unit. The magnetic reconfiguration unit is arranged around an outer periphery of the permanent magnet rotor, and a coil connected to a control circuit is wound on an outer layer of the magnetic reconfiguration unit. When it is necessary to execute low rotation speed or zero rotation speed operating conditions, the control circuit inputs current pulses of different strengths, so that the magnetic reconfiguration unit obtains permanent magnetization of corresponding degree, and generates a magnetic field which acts together with a magnetic field of the permanent magnet rotor, so as to maintain a torque required for output.
