A Note On Side-Channels Resulting From Dynamic Compilation

D. Page

Abstract: Dynamic compilation systems are of fundamental importance to high performance execution of interpreted languages such as Java. These systems analyse the performance of an application at run-time and aggressively re-compile and optimise code which is deemed critical to performance. However, the premise that the code executed is not the same code as written by the programmer raises a number of important security concerns. In this paper we examine the specific problem that dynamic compilation, through transformation of the code, may introduce side-channel vulnerabilities where before there were none.
