text: 'Wettstreit zwischen der Entwicklung neuer Hardwaretrojaner und entsprechender
Gegenmaßnahmen beschreiten Widersacher immer raffiniertere Wege um Schaltungsentwürfe
zu infizieren und dabei selbst fortgeschrittene Test- und Verifikationsmethoden
zu überlisten. Abgesehen von den konventionellen Methoden um einen Trojaner in
eine Schaltung für ein Field-programmable Gate Array (FPGA) einzuschleusen, können
auch die Entwurfswerkzeuge heimlich kompromittiert werden um einen Angreifer dabei
zu unterstützen einen erfolgreichen Angriff durchzuführen, der zum Beispiel Fehlfunktionen
oder ungewollte Informationsabflüsse bewirken kann. Diese Dissertation beschäftigt
sich hauptsächlich mit den beiden Blickwinkeln auf Hardwaretrojaner in rekonfigurierbaren
Systemen, einerseits der Perspektive des Verteidigers mit einer Methode zur Erkennung
von Trojanern auf der Bitstromebene, und andererseits derjenigen des Angreifers
mit einer neuartigen Angriffsmethode für FPGA Trojaner. Für die Verteidigung gegen
den Trojaner ``Heimtückische LUT'''' stellen wir die allererste erfolgreiche Gegenmaßnahme
vor, die durch Verifikation mittels Proof-carrying Hardware (PCH) auf der Bitstromebene
direkt vor der Konfiguration der Hardware angewendet werden kann, und präsentieren
ein vollständiges Schema für den Entwurf und die Verifikation von Schaltungen
für iCE40 FPGAs. Für die Gegenseite führen wir einen neuen Angriff ein, welcher
bösartiges Routing im eingefügten Trojaner ausnutzt um selbst im fertigen Bitstrom
in einem inaktiven Zustand zu verbleiben: Hierdurch kann dieser neuartige Angriff
zur Zeit weder von herkömmlichen Test- und Verifikationsmethoden, noch von unserer
vorher vorgestellten Verifikation auf der Bitstromebene entdeckt werden.'

text: The battle of developing hardware Trojans and corresponding countermeasures
has taken adversaries towards ingenious ways of compromising hardware designs
by circumventing even advanced testing and verification methods. Besides conventional
methods of inserting Trojans into a design by a malicious entity, the design flow
for field-programmable gate arrays (FPGAs) can also be surreptitiously compromised
to assist the attacker to perform a successful malfunctioning or information leakage
attack. This thesis mainly focuses on the two aspects of hardware Trojans in reconfigurable
systems, the defenders perspective which corresponds to the bitstream-level Trojan
detection technique, and the attackers perspective which corresponds to a novel
FPGA Trojan attack. From the defender's perspective, we introduce a first-ever
successful pre-configuration countermeasure against the ``Malicious LUT''-hardware
Trojan, by employing bitstream-level Proof-Carrying Hardware (PCH) and present
the complete design-and-verification flow for iCE40 FPGAs. Likewise, from an attackers
perspective, we present a novel attack that leverages malicious routing of the
inserted Trojan circuit to acquire a dormant state even in the generated and transmitted
bitstream. Since the Trojan is injected in a post-synthesis step and remains unconnected
in the bitstream, the presented attack can currently neither be prevented by conventional
testing and verification methods nor by bitstream-level verification techniques.

text: "Previous research in proof-carrying hardware has established the feasibility
and utility of the approach, and provided a concrete solution for employing it
for the certification of functional equivalence checking against a specification,
but fell short in connecting it to state-of-the-art formal verification insights,
methods and tools. Due to the immense complexity of modern circuits, and verification
challenges such as the state explosion problem for sequential circuits, this restriction
of readily-available verification solutions severely limited the applicability
of the approach in wider contexts.\r\n\r\nThis thesis closes the gap between the
PCH approach and current advances in formal hardware verification, provides methods
and tools to express and certify a wide range of circuit properties, both functional
and non-functional, and presents for the first time prototypes in which circuits
that are implemented on actual reconfigurable hardware are verified with PCH methods.
Using these results, designers can now apply PCH to establish trust in more complex
circuits, by using more diverse properties which they can express using modern,
efficient property specification techniques."

und Nützlichkeit gezeigt und einen Ansatz zur Zertifizierung der funktionalen
Äquivalenz zu einer Spezifikation geliefert, jedoch ohne PCH mit aktuellen Erkenntnissen,
Methoden oder Werkzeugen formaler Hardwareverifikation zu verknüpfen. Aufgrund
der Komplexität moderner Schaltungen und Verifikationsherausforderungen wie der
Zustandsexplosion bei sequentiellen Schaltungen, limitiert diese Einschränkung
sofort verfügbarer Verifikationslösungen die Anwendbarkeit des Ansatzes in einem
größeren Kontext signifikant.\r\n\r\nDiese Dissertation schließt die Lücke zwischen
PCH und modernen Entwicklungen in der Schaltungsverifikation und stellt Methoden
und Werkzeuge zur Verfügung, welche die Zertifizierung einer großen Bandbreite
von Schaltungseigenschaften ermöglicht; sowohl funktionale, als auch nicht-funktionale.
Überdies werden erstmals Prototypen vorgestellt in welchen Schaltungen mittels
PCH verifiziert werden, die auf tatsächlicher rekonfigurierbarer Hardware realisiert
sind. Dank dieser Ergebnisse können Entwickler PCH zur Herstellung von Vertrauen
in weit komplexere Schaltungen verwenden, unter Zuhilfenahme einer größeren Vielfalt

text: Traditional cache design uses a consolidated block of memory address bits
to index a cache set, equivalent to the use of modulo functions. While this module-based
mapping scheme is widely used in contemporary cache structures due to the simplicity
of its hardware design and its good performance for sequences of consecutive addresses,
its use may not be satisfactory for a variety of application domains having different
characteristics.This thesis presents a new type of cache mapping scheme, motivated
by programmable capabilities combined with Nature-inspired optimization of reconfigurable
hardware. This research has focussed on an FPGA-based evolvable cache structure
of the first level cache in a multi-core processor architecture, able to dynamically
change cache indexing. To solve the challenge of reconfigurable cache mappings,
a programmable Boolean circuit based on a combination of Look-up Table (LUT) memory
elements is proposed. Focusing on optimization aspects at the system level, a
Performance Measurement Infrastructure is introduced that is able to monitor the
underlying microarchitectural metrics, and an adaptive evaluation strategy is
presented that leverages on Evolutionary Algorithms, that is not only capable
of evolving application-specific address-to-cache-index mappings for level one
split caches but also of reducing optimization times. Putting this all together
and prototyping in an FPGA for a LEON3/Linux-based multi-core processor, the creation
of a system architecture reduces cache misses and improves performance over the
use of conventional caches.

text: Traditionelle Cachedesigns verwenden konsolidierte Blöcke von Speicheradressbits
um einen Cachesatz zu indizieren, vergleichbar mit der Anwendung einer Modulofunktion.
Obwohl dieses modulobasierte Abbildungsschema in heutigen Cachestrukturen weit
verbreitet ist, vor allem wegen seiner einfachen Anforderungen an das Hardwaredesign
und seiner Effizienz für die Indizierung eufeinanderfolgender Speicheradressen,
kann seine Verwendung für eine Vielzahl von Anwendungsdomänen mit unterschiedlichen
Charakteristiken zu suboptimalen Ergebnissen führen. Diese Dissertation präsentiert
einen neuen Typ von Cacheabbildungsschema, motiviert durch die Kombination programmierbarer
Ressourcen mit der naturinspirierten Optimierung rekonfigurierbarer Hardware.
Im Fokus dieser Forschung steht eine FPGA-basierte Cachestruktur für den first
level Cache einer Mehrkernprozessorarchitektur, welche die Cacheindizierung dynamisch
ändern kann. Um die Herausforderung rekonfigurierbarer Cacheabbildungen zu lösen,
wird eine reprogrammierbare Boolesche Schaltung eingeführt, die auf Look-up Table
(LUT) Speicherelementen basiert. Weiterhin wird eine Infrastruktur zur Effizienzmessung
eingeführt, welche die zugrundeliege Mikroarchitektur überwachen kann, sowie eine
adaptive Evaluationsstrategie präsentiert, die evolutionäre Algorithmen wirksam
einsetzt, und die nicht nur anwendungsspezifische Abbildungen von Speicheradressen
zu Cacheindizes für level one Caches evolvieren sondern dabei auch die Optimierungszeiten
reduzieren kann. All diese Aspekte zusammen in einer prototypischen Implementierung
auf einem FPGA für einen LEON3/Linux-basierten Mehrkernprozessor zeigen, dass
evolvierbare Cacheabbildungsfunktionen Cache Misses reduzieren, sowie die Effizienz
im Vergleich zu konventionellen Caches erhöhen können.

text: "The use of heterogeneous computing resources, such as graphics processing
units or other specialized co-processors, has become widespread in recent years
because of their performance and energy efficiency advantages. Operating system
approaches that are limited to optimizing CPU usage are no longer sufficient for
the efficient utilization of systems that comprise diverse resource types.\r\n\r\nEnabling
task preemption on these architectures and migration of tasks between different
resource types at run-time is not only key to improving the performance and energy
consumption but also to enabling automatic scheduling methods for heterogeneous
compute nodes.\r\n\r\nThis thesis proposes novel techniques for run-time management
of heterogeneous resources and enabling tasks to migrate between diverse hardware.
It provides fundamental work towards future operating systems by discussing implications,
limitations, and chances of the heterogeneity and introducing solutions for energy-
and performance-efficient run-time systems. Scheduling methods to utilize heterogeneous
systems by the use of a centralized scheduler are presented that show benefits
over existing approaches in varying case studies."

text: "Monte-Carlo Tree Search (MCTS) is a class of simulation-based search algorithms.
It brought about great success in the past few years regarding the evaluation
of deterministic two-player games such as the Asian board game Go.\r\n\r\nIn this
thesis, we present a parallelization of the most popular MCTS variant for large
HPC compute clusters that efficiently shares a single game tree representation

order to measure the impact of our parallelization on the search quality and remain
comparable to the most advanced MCTS implementations to date, we implemented it
in a state-of-the-art Go engine Gomorra, making it competitive with the strongest
Go programs in the world.\r\n\r\nWe further present an empirical comparison of
different Bayesian ranking systems when being used for predicting expert moves
for the game of Go and introduce a novel technique for automated detection and

text: "Reconfigurable circuit devices have opened up a fundamentally new way of
creating adaptable systems. Combined with artificial evolution, reconfigurable
circuits allow an elegant adaptation approach to compensating for changes in the
distribution of input data, computational resource errors, and variations in resource
requirements. Referred to as ``Evolvable Hardware'' (EHW), this paradigm has yielded
astonishing results for traditional engineering challenges and has discovered
intriguing design principles, which have not yet been seen in conventional engineering.\r\n\r\nIn
this thesis, we present new and fundamental work on Evolvable Hardware motivated
by the insight that Evolvable Hardware needs to compensate for events with different
change rates. To solve the challenge of different adaptation speeds, we propose
a unified adaptation approach based on multi-objective evolution, evolving and
propagating candidate solutions that are diverse in objectives that may experience
radical changes.\r\n\r\nFocusing on algorithmic aspects, we enable Cartesian Genetic
Programming (CGP) model, which we are using to encode Boolean circuits, for multi-objective
optimization by introducing a meaningful recombination operator. We improve the
scalability of CGP by objectives scaling, periodization of local- and global-search
algorithms, and the automatic acquisition and reuse of subfunctions using age-
and cone-based techniques. We validate our methods on the applications of adaptation
of hardware classifiers to resource changes, recognition of muscular signals for
prosthesis control and optimization of processor caches."

text: 'Handling run-time dynamics on embedded system-on-chip architectures has become
more challenging over the years. On the one hand, the impact of workload and physical
dynamics on the system behavior has dramatically increased. On the other hand,
embedded architectures have become more complex as they have evolved from single-processor
systems over multi-processor systems to hybrid multi-core platforms.Static design-time
techniques no longer provide suitable solutions to deal with the run-time dynamics
of today''s embedded systems. Therefore, system designers have to apply run-time
solutions, which have hardly been investigated for hybrid multi-core platforms.In
this thesis, we present fundamental work in the new area of run-time management
on hybrid multi-core platforms. We propose a novel architecture, a self-adaptive
hybrid multi-core system, that combines heterogeneous processors, reconfigurable
hardware cores, and monitoring cores on a single chip. Using self-adaptation on
thread-level, our hybrid multi-core systems can effectively perform performance
and thermal management autonomously at run-time. '

text: FPGAs, systems on chip and embedded systems are nowadays irreplaceable. They
combine the computational power of application specific hardware with software-like
flexibility. At runtime, they can adjust their functionality by downloading new
hardware modules and integrating their functionality. Due to their growing capabilities,
the demands made to reconfigurable hardware grow. Their deployment in increasingly
security critical scenarios requires new ways of enforcing security since a failure
in security has severe consequences. Aside from financial losses, a loss of human
life and risks to national security are possible. With this work I present the
novel and groundbreaking concept of proof-carrying hardware. It is a method for
the verification of properties of hardware modules to guarantee security for a
target platform at runtime. The producer of a hardware module delivers based on
the consumer's safety policy a safety proof in combination with the reconfiguration
bitstream. The extensive computation of a proof is a contrast to the comparatively
undemanding checking of the proof. I present a prototype based on open-source
tools and an abstract FPGA architecture and bitstream format. The proof of the
usability of proof-carrying hardware provides the evaluation of the prototype
with the exemplary application of securing combinational and bounded sequential
equivalence of reference monitor modules for memory safety.

text: FPGAs, System on Chips und eingebettete Systeme sind heutzutage kaum mehr
wegzudenken. Sie kombinieren die Rechenleistung von spezialisierter Hardware mit
einer Software-ähnlichen Flexibilität. Zur Laufzeit können sie ihre Funktionalität
anpassen, indem sie online neue Hardware Module beziehen und deren Funktionalität
integrieren. Mit der Leistung wachsen auch die Anforderungen an rekonfigurierbare
Hardware. Ihr Einsatz in immer sicherheitskritischeren Szenarien erfordert neue
Wege um Sicherheit zu gewährleisten, da ein Versagen der Sicherheit gravierende
Folgen mit sich bringt. Neben finanziellen Verlusten sind auch der Verlust von
Menschenleben oder Einbußen in der nationalen Sicherheit denkbar. In dieser Arbeit
stelle ich das neue und wegweisende Konzept der beweistragenden Hardware vor.
Es ist eine Methode zur Verifizierung von Eigenschaften von Hardware Modulen um
die Sicherheit der Zielplatformen zur Laufzeit zu garantieren. Der Produzent eines
Hardware Moduls liefert, basierend auf den Sicherheitsbestimmungen des Konsumenten,
einen Beweis der Sicherheit mit dem Rekonfigurierungsbitstrom. Die aufwendige
Berechnung des Beweises steht im Kontrast zu der vergleichsweise unaufwendigen
Überprüfung durch den Konsumenten. Ich präsentiere einen Prototypen basierend
auf Open Source Werkzeugen und einer eigenen abstrakten FPGA Architektur samt
Bitstromformat. Den Nachweis über die Nutzbarkeit von beweistragender Hardware
erbringt die Evaluierung des Prototypen zur beispielhaften Anwendung der Sicherung
von kombinatorischer und begrenzt sequenzieller Äquivalenz von Referenzmonitor-Modulen
zur Speichersicherheit.

text: "The paradigm shift towards many-core parallelism is accompanied by two fundamental
questions: how should the many processors on a single die communicate to each
other and what are suitable programming models for these novel architectures?
In this thesis, the author tackles both questions by reviewing the reconfigurable
mesh model of massively parallel computation for many-cores.\r\n\r\nThe book presents
the design, implementation and evaluation of a many-core architecture that is
based on the execution principles and communication infrastructure of the reconfigurable
mesh. This work fundamentally rests on FPGA implementations and shows that reconfigurable
mesh processors with hundreds of autonomous cores are feasible. Several case studies
demonstrate the effectiveness of programming and illustrate why the reconfigurable
mesh is a promising model for many-cores."
