Full textWe offer a secure hardware architecture for system boot up, secure software execution and on field update. A new scheme is presented to guarantee dat confidentiality and integrity for off-chip memories. The architecture capabilities are extended to support on the fly security level management of data. The goal is to minimize the overhead due to security like logic area, performance, memory footprint and power consumption for the architecture. After careful evaluation through real time applications execution with this secure architecture, the next step was to provide an end to end solution. Toward th solution, a secure boot up mechanism is proposed in order to securely start applications from a flash memory. More techniques are also introduced to allow on field software update for later secure execution with the architecture. A complete set ofresults has been generated in order to underline the fact that the proposed solution matches with the current needs and constraints of embedded systems. For the first time the security cost in area, performance, memory and power has been evaluated for embedded systems with an end to end solution

Full textThe majority of the solutions to the issue of computer security (algorithms, protocols, secure operating systems, applications) are running on insecure hardware architectures that may be vulnerable to physical (bus spying, modification of the memory content, etc. ) or logical (malicious operating system) attacks. Several secure architectures, which are able to protect the confidentiality and the correct execution of programs against such attacks, have been proposed for several years. After the presentation of some cryptographic bases and a review of the main secure architectures proposed in the litterature, we will present the secure architecture CryptoPage. This architecture guarantees the confidentiality of the code and the data of applications and the correct execution against hardware or software attacks. In addition, it also includes a mechanism to reduce the information leakage on the address bus, while keeping reasonable performances. We will also study how to delegate some security operations of the architecture to an untrusted operating system in order to get more flexibility but without compromising the security of thearchitecture. Finally, some other important mechanism are studied: encrypted processid entification, attestations of the results, management of software signals, management of the threads, inter-process communication

Full textcomme des hôtes de confiance car toute personne y ayant accès, sont des attaquants potentiels. Les données
contenues dans ces systèmes peuvent être sensibles (données privées du propriétaire, mot de passe, code d'un
logiciel...) et sont généralement échangées en clair entre le Système sur Puces (SoC – System on Chip) et la
mémoire dans laquelle elles sont stockées. Le bus qui relie ces deux entités constitue donc un point faible : un
attaquant peut observer ce bus et récupérer le contenu de la mémoire, ou bien a la possibilité d'insérer du code
afin d'altérer le fonctionnement d'une application s'exécutant sur le système. Afin de prévenir ce type d'attaque,
des mécanismes matériels doivent être mis en place afin d'assurer la confidentialité et l'intégrité des données.
L'approche conventionnelle pour atteindre cet objectif est de concevoir un mécanisme matériel pour chaque
service de sécurité (confidentialité et intégrité). Cette approche peut être implantée de manière sécurisée mais
empêche toute parallélisation des calculs sous-jacents.
Les travaux menés au cours de cette thèse ont dans un premier temps, consisté à faire une étude des
techniques existantes permettant d'assurer la confidentialité et l'intégrité des données. Dans un deuxième temps,
nous avons proposé deux mécanismes matériels destinés à la sécurisation des transactions entre un processeur et
sa mémoire. Un moteur de chiffrement et de contrôle d'intégrité parallélisé, PE-ICE (Parallelized Encryption and
Integrity Checking Engine) a été conçu. PE-ICE permet une parallélisation totale des opérations relatives à la
sécurité aussi bien en écriture qu'en lecture de données en mémoire. Par ailleurs, une technique basée sur une
structure d'arbre (PRV-Tree – PE-ICE protected Reference Values) comportant la même propriété de
parallélisation totale, a été spécifiée afin de réduire le surcoût en mémoire interne impliqué par les mécanismes de sécurité

Full textNowadays, digital security is of major importance to our societies. Communications, energy, transport, means of production, Internet of Things… The use of digital systems is ever increasing, making them critical to the correct working of our world. A little more than two decades ago, a new form of attack has risen: fault injection. Essentially, it consists in perturbing a circuit during computation, using various methods such as power glitches, electromagnetic injection or laser injection; in the aim of generating errors. These errors can then be exploited by an attacker to reveal secret information from the circuit, or to bypass some security measures.System complexification and technological advances make digital systems particularly vulnerable against fault injection attacks. In order to thwart these attacks effectively and at a reasonable cost, it is necessary to consider security from the early phases of the design flow. To do that, a better understanding of how faults impact processors is required. Effects provoked by fault injection can be modeled at various levels of abstraction. Currently, if the impact of faults at the hardware level is relatively well known, the same cannot be said for the software level. Security analyses at the software level are based on simple software fault models such as instruction skip, register corruption or test inversion. These models are applied without any serious consideration for the microarchitecture of the attacked processor. This brings the question of the realism of these models, leading to two types of problems: some modeled effects do not correspond to actual attacks; and, conversely, some effects lowering the security of the system are not modeled. These issues then translate to over-engineered, or, worse, under-engineered countermeasures.To face the limitations of typical software fault models, a precise study of processor microarchitectures is necessary. In this thesis, we first explore how various structures of the processor, such as the pipeline or optimization structures like forwarding and speculative execution, can influence the behavior of faults in the inner working of the processor; and how they call into question a pure software vision of how faults impact software execution. RTL injections are conducted in a RISC-V processor, to demonstrate how these effects could be exploited to counter typical software countermeasures and a hardened program that check PIN codes. Then, a method to study more generally the effects of faults in a processor is developed. The point of this method is twofold. The first is about modeling faults at the software level, with the definition of several metrics to evaluate models. The second point is about keeping a link to the RTL level, in order to be able to materialize effects obtained at the software level. Finally, to end this thesis, we study the possibility to use static analysis to analyze the security of programs against software fault models defined previously. Two methods are considered, one using abstract interpretation, and the other using symbolic execution.This thesis, financed by the IRT Nanoelec for the Pulse project, has been conducted within the LCIS laboratory in Valence, in collaboration with the CEA-Leti in Grenoble. It has been supervised by Vincent Beroulle (LCIS), and co-supervised by Christophe Deleuze (LCIS) and Florian Pebay-Peyroula (CEA-Leti)

Full textInformation flow control (also known as Dynamic Information Flow Tracking, DIFT), allows a user to detect several types of software attacks such as buffer overflow or SQL injections. In this thesis, a solution based on the ARM Cortex-A9 processor family is proposed. Our approach relies on the use of ARM CoreSight components, which are able to trace software as executed by the processor in order to perform the information flow tracking. The DIFT coprocessor proposed in this thesis is implemented in an Artix-7 FPGA, embedded in a System-on-Chip (SoC) Zynq provided by Xilinx. It is shown that using ARM CoreSight components does not add a latency overhead while giving a better communication time between the ARM processor and the DIFT coprocessor
