"Conception de matériel salutaire pour lutter contre la contrefaçon et le vol de circuits intégrés."


Counterfeiting and theft affects all industrial activities in our society. Electronic products are the second category of products most concerned by these issues. Among the most affected electronic products, we find mobile phones, tablets, computers as well as more basic elements such as analog and digital circuits or integrated circuits. These are the heart of almost all electronic products and we can say that a mobile phone is counterfeit if it has at least one counterfeit integrated circuit inside. The market of counterfeit integrated circuit is estimated between 7 and 10% of the global semi-conductors market, which represents a loss of at least 24 billion euros for the lawful industry in 2015. These losses could reach 36 billion euros in 2016. Therefore, there is an absolute necessity to find practical and efficient methods to fight against counterfeiting and theft of integrated circuits.
The SALWARE project, granted by the french "Agence Nationale de la Recherche" and by the "Fondation de Recherche pour l'Aéronautique et l'Espace", aims to fight against the problem of counterfeiting and theft of integrated circuits. For that, we propose to design salutary hardwares (salwares). More specifically, we propose to cleverly combine different protection mechanisms to build a complete activation system. Activate an integrated circuit after its manufacturing helps to restore the control of integrated circuits to the true owner of the intellectual property.
In this thesis, we propose the study of three different protection mechanisms fighting against counterfeiting and theft of integrated circuits. First, the insertion and the detection of watermark in the finite state machine of digital and synchronous systems will be studied. This mechanism helps to detect counterfeit or theft parts. Then, a physical unclonable function based on transient effect ring oscillator is implemented and characterized on FPGA. This protection mechanism is used to identify integrated circuit with a unique identifier created thanks to the extraction of entropy from manufacturing process variations. Finally, we discuss the hardware implementations of lightweight block ciphers, which establish a secure communication during the activation of an integrated circuit.
