Résumé :

Side channel attacks take advantage of information leakagesin cryptographic devices. Template attacks form a family of side channelattacks which is reputed to be extremely effective. This kind of attacksassumes that the attacker fully controls a cryptographic device before at-tacking a similar one. In this paper, we propose to relax this assumption bygeneralizing the template attack using a method based on a semi-supervisedlearning strategy. The effectiveness of our proposal is confirmed by softwaresimulations, by experiments on a 8-bit microcontroller and by a comparisonto a template attack as well as to two supervised machine learning methods.
