Abstract

A method for detecting a cache-based side-channel attack includes utilizing a timer thread that continuously increments a variable in code of an application. The code has been instrumented such that the instrumented code uses the variable incremented by the timer thread to infer an amount of time taken for running a part of the code. A number of cache misses during execution of the part of the code is determined based on the amount of time. It is determined whether the application is experiencing the cache-based side-channel attack using a classifier which uses as input the number of cache misses.
