High-Assurance Software

At HASLab, we anchor our research on a rigorous approach to three areas of Computer Science: Software Engineering, Distributed Systems, and Cryptography and Information Security.

Our contributions to these areas range from fundamental research on formal methods and algorithms, to applied research on the development of tools and middleware that address real-world demands stemming from long-term collaborations with industry.

SafeCloud promotes the privacy and integrity of cloud utilization

On 27 September, took place the third and final assessment by the European Commission of the SafeCloud project. The project was led by INESC TEC's High-Assurance Software Laboratory (HASLab). With an investment of over three million euros, the project focused on the area of  cloud infrastructures that, despite their many advantages, still present several challenges of privacy and integrity to data storage and processing.

Runtime verification of autopilot systems using a fragment of MTL-?

Abstract
Current real-time embedded systems development frameworks lack support for the verification of properties using explicit time where counting time (i.e., durations) may play an important role in the development process. Focusing on the real-time constraints inherent to these systems, we present a framework that addresses the specification of duration properties for runtime verification by employing a fragment of metric temporal logic with durations. We also provide an overview of the framework, the synthesis tools, and the library to support monitoring properties for real-time systems developed in C++11. The results obtained provide clear evidence of the feasibility and advantages of employing a duration-sensitive formalism to increase the dependability of avionic controller systems such as the PX4 and the Ardupilot flight stacks. © 2017 Springer-Verlag GmbH Germany

Delta State replicated data types

JOURNAL OF PARALLEL AND DISTRIBUTED COMPUTING

Abstract
Conflict-free Replicated Data Types (CRDTs) are distributed data types that make eventual consistency of a distributed object possible and non ad-hoc. Specifically, state-based CRDTs ensure convergence through disseminating the entire state, that may be large, and merging it to other replicas. We introduce Delta State Conflict-Free Replicated Data Types (delta-CRDT) that can achieve the best of both operation-based and state-based CRDTs: small messages with an incremental nature, as in operation-based CRDTs, disseminated over unreliable communication channels, as in traditional state-based CRDTs. This is achieved by defining delta-mutators to return a delta-state, typically with a much smaller size than the full state, that to be joined with both local and remote states. We introduce the delta-CRDT framework, and we explain it through establishing a correspondence to current state-based CRDTs. In addition, we present an anti-entropy algorithm for eventual convergence, and another one that ensures causal consistency. Finally, we introduce several delta-CRDT specifications of both well-known replicated datatypes and novel datatypes, including a generic map composition.
