Precise Instruction-Level Side Channel Profiling of Embedded Processors
Since the first publication, side channel leakage has been widely used for the purposes of extracting secret information, such as cryptographic keys, from embedded devices.However, in a few instances it has been utilised for extracting other information about the internal state of a computing device.In this paper, we show how to create a precise instruction-level side channel leakage profile of an embedded pro cessor.Using the profile we show how to extract executed instructions from the devices leakage with high accuracy.In addition, we provide a comparison between several performance and recognition enhancement tools.Further, we also provide details of our lab setup and noise minimi sation techniques, and suggest possible applications.
