Abstract

A crucial problem in computer security is detecting information leakage via side channels. Information gained by observing non-functional properties of program executions (such as execution time or memory usage) can enable attackers to infer secret information accessed by the program. In this talk, I will discuss how symbolic execution, combined with a model counting constraint solver, can be used for detecting and quantifying side-channel leakage in programs, and also for identifying input sequences that can be used to recover secrets. I will also discuss how we implemented this approach by extending symbolic execution with our model counting constraint solver ABC.
