A Template Attack Against VERIFY PIN Algorithms

Abstract : This paper presents the first side channel analysis from electromagnetic emissions on VERIFY PIN algorithms. To enter a PIN code, a user has a limited number of trials. Therefore the main difficulty of the attack is to succeed with very few traces. More precisely, this work implements a template attack and experimentally verifies its success rate. It becomes a new real threat, and it is feasible on a low cost and portable platform. Moreover, this paper shows that some protections for VERIFY PIN algorithms against fault attacks introduce new vulnerabilities with respect to side channel analysis.
