Invited Talk: Security by Compilation: An Automated Approach to Side-channel Resistance
Programmers often view the computing devices as black-boxes, but real computers leak information of the software they execute through various side channels, e.g., variations in power dissipation, radiation, execution time, and sound signature of the processor. Side-channel information may be exploited by adversaries. For example, while cryptographic algorithms may be secure against hundreds of years of brute-force attacks, their actual implementations may be broken in hours or even minutes in the presence of side-channel leaks. In this talk, I will explain how formal verification and program synthesis can be used to (1) detect side-channel leaks of software code running on IoT devices, (2) prove the absence of side-channel leaks, and (3) transform software to eliminate such leaks. We use power side-channel leaks in cryptographic software as examples, but the underlying techniques are applicable to other types of side channels and software systems as well.
