Abstract

We describe an SPA power attack on an 8-bit implementation of AES. Our attack uses an optimized search of the key space to improve upon previous work in terms of speed, flexibility, and handling of data error. We can find a 128-bit cipher key in 16ms on average, with similar results for 192- and 256-bit cipher keys. The attack almost always produces a unique cipher key and performs well even in the presence of substantial measurement error.
