Détection et prévention de Cheval de Troie Matériel (CTM) par des méthodes Orientées Test Logique

Abstract : In order to reduce the production costs of integrated circuits (ICs), outsourcing the fabrication process has become a major trend in the Integrated Circuits (ICs) industry. As an inevitable unwanted side effect, this outsourcing business model increases threats to hardware products. This process raises the issue of un-trusted foundries in which, circuit descriptions can be manipulated with the aim to possibly insert malicious circuitry or alterations, referred to as Hardware Trojan Horses (HTHs). This motivates semiconductor industries and researchers to study and investigate solutions for detecting during testing and prevent during fabrication, HTH insertion.However, considering the stealthy nature of HTs, it is quite impossible to detect them with conventional testing or even with random patterns. This motivates us to make some contributions in this thesis by proposing solutions to detect and prevent HTH after fabrication (during testing).The proposed methods help to detect HTH as well during testing as during normal mode(run-time), and they are logic testing based.Furthermore, we propose prevention methods, which are also logic testing based, in order tomake harder or quasi impossible the insertion of HTH both in netlist and layout levels.
