Low voltage fault attacks to AES

Abstract

This paper presents a new fault based attack on the Advanced Encryption Standard (AES) with any key length, together with its practical validation through the use of low voltage induced faults. The CPU running the attacked algorithm is the ARM926EJ-S: a 32-bit processor widely deployed in computer peripherals, telecommunication appliances and low power portable devices. We prove the practical feasibility of this attack through inducing faults in the computation of the AES algorithm running on a full fledged Linux 2.6 operating system targeted to two implementations of the ARM926EJ-S on commercial development boards.
