Breaking Encryption with an Oscilloscope: An Introduction to Power Analysis Attacks

Presented at THOTCON 0x5 (2014), April 25, 2014, 11 a.m. (50 minutes).

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.
