Data-driven intelligent applications in modern online services have become ubiquitous.
These applications are usually hosted in the untrusted cloud computing infrastructure. This …

Library OSs have been proposed to deploy applications isolated inside containers, VMs, or
trusted execution environments. They often follow a highly modular design in which third …

The growing interest in reliable multi-party applications has fostered widespread adoption of
Byzantine Fault-Tolerant (bft) consensus protocols. Existing bft protocols need f more …

The emergence of blockchain technology has renewed the interest in consensus-based
data management systems that are resilient to failures. To maximize the throughput of these …

While the number of connected devices is constantly growing, we observe an increased
incident rate of cyber attacks that target user data. Typically, personal devices contain the …

With in-memory key-value caches such as Redis and Memcached being a key component
for many systems to improve throughput and reduce latency, cloud caches have been widely …

Trusted execution environments (TEEs) promise a cost-effective,“lift-and-shift” solution for
deploying security-sensitive applications in untrusted clouds. For this, they must support rich …

This paper introduces HotStuff-1, a BFT consensus protocol that improves the latency of
HotStuff-2 by two network-hops while maintaining linear communication complexity against …

Light clients have been widely used in blockchain systems to support lightweight nodes by
synchronizing and verifying block headers only. However, there are two major limitations …

Intel SGX improves the security of applications by shielding code and data from untrusted
software in enclaves. Since enclaves lose their state when closed, that state has to be …
