Breaking Encryption with an Oscilloscope: Power Analysis for Software Hackers

Seminar from toorcon 16 Side channel attacks against hardware targets often appear difficult to software specialists. Power analysis attacks are a class of side channel attacks relying on sampling a devices power consumption during cryptographic operations. This talk will focus on setup and implementation for differential power analysis attacks against DES and include a brief overview of both simple and template power analysis attacks. We begin with an introduction to power analysis attacks, hardware requirements and setup. Then, an implementation of a differential power analysis attack will be shown against a simple target.
