Abstract SAFETY-CRITICAL APPLICATIONS have to function correctly and deliver high level
of quality-of-service even in the presence of faults. This thesis deals with techniques for …

This paper introduces the fundamental concepts of fault tolerant computing. Key topics
covered are voting, fault detection, clock synchronization, Byzantine Agreement, diagnosis …

Fault tolerance is a key obstacle to next generation extreme-scale systems. As systems
scale, the Mean Time To Interrupt (MTTI) decreases proportionally. As a result, extreme …

Trusted Execution Environments (TEEs) ensure the confidentiality and integrity of
computations in hardware. Subject to the TEE's threat model, the hardware shields a …

The problem of replica coordination is fundamental to building Byzantine fault-tolerant (BFT)
distributed systems. Seminal BFT architectures for safety-critical real-time systems from the …

Even with the rise of cyberattacks on high-value systems, we still do not see widespread
adoption of intrusion-tolerant replication protocols, despite their long history in the research …

The state machine replication technique is a popular approach for building Byzantine fault-
tolerant services. However, despite the widespread adoption of this paradigm for crash fault …

Many crucial dependable and secure services including atomic commitment, consensus and
group membership, and middleware services (such as replica, communication and …

The overall performance improvement in Byzantine fault-tolerant state machine replication
algorithms has made them a viable option for critical high-performance systems. However …
