Side Channel Leakage Profiling in Software

Testing cryptographic implementations for side channel leakage is a difficult and important

problem. The techniques used to uncover side channel leakage are more involved

than the usual methodologies of software testing, for example sometimes involving physical

measurements of hardware. As such, it is difficult to work this sort of analysis into

the usual software testing process. To this end we have developed the side channel profiler. This is an extensible framework for capturing dynamic execution of cryptographic

code and applying side channel analysis regardless of underlying architecture. This tool

can be used to selectively emulate different hardware components, or apply other side

channel leakage criteria. We also demonstrate how the tool can be used to analyze an

implementation of naive square and multiply modular exponentiation.
