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.

Keyruptive is INESC TEC's most recent spin-off

Keyruptive is INESC TEC's most recent spin-off and it operates in the IT security area. It was born in Braga, being the result of a work of many years from a group of researchers of INESC TEC’s High-Assurance Software Laboratory (HASLab), and already has a technology solution to present to the market, whose name is the same as the company that was created.

Predicting throughput in IEEE 802.11 based wireless networks using directional antenna

Abstract
In IEEE 802.11 based wireless networks interference increases as more access points are added. A metric helping to quantize this interference seems to be of high interest. In this paper we study the relationship between the (Formula presented.) metric, which captures interference, and throughput for IEEE 802.11 based network using directional antenna. The (Formula presented.) model was found to best represent the relationship between the interference metric and the network throughput. We use this model to predict the performance of similar networks and decide the best configuration a network operator could use for planning his network. © 2017 Springer Science+Business Media, LLC

Memoized zipper-based attribute grammars and their higher order extension

Fernandes, JP; Martins, P; Pardo, A; Saraiva, J; Viera, M;

Publication
Science of Computer Programming

Abstract
Attribute grammars are a powerfull, well-known formalism to implement and reason about programs which, by design, are conveniently modular. In this work we focus on a state of the art zipper-based embedding of classic attribute grammars and higher-order attribute grammars. We improve their execution performance through controlling attribute (re)evaluation by means of memoization techniques. We present the results of our optimizations by comparing their impact in various implementations of different, well-studied, attribute grammars and their Higher-Order extensions. © 2018 Elsevier B.V.
