Abstract
A method for analyzing side-channel leakage of an application running on a device including loading the application on a system comprising a device simulator, wherein the application is configured to accept public inputs and secret inputs and selecting a set of public inputs. The method includes, for each public input in the set of public inputs, executing the application on the system comprising the device simulator based on a respective public input and a first value for a secret input and extracting first intermediate values for the simulated device, and executing the application on the system based on the respective public input and a second value for the secret input and extracting second intermediate values for the simulated device. The method includes determining an amount of dependency of a location of the simulated device on the secret input based on a plurality of the first and second intermediate values.
