High-Assurance Software

At the High-Assurance Software Laboratory (HASLab), we improve practice through theory, creating and implementing software that goes beyond mere functionality: we ensure it is correct, resilient, and secure against failures and attacks.


Our team of researchers, scientists, and engineers has proven expertise in software engineering, developing methods and tools to design and integrate robust software; in distributed systems, exploring distribution and replication to ensure scalability and reliability; and in information security, addressing cybersecurity challenges and improving systems with advanced, secure cryptographic protocols, thus minimising vulnerabilities.


With a multidisciplinary approach supported by solid theoretical principles, we develop innovative solutions for critical software, secure cloud infrastructures, and privacy-aware big data management, driving scientific advancement, innovation, and high-level consultancy.


In addition, we complement our core expertise with work in human-computer interaction, programming languages, computational mathematics, and quantum computing - because we believe the future of trustworthy software is built on knowledge and innovation.

Automating Code Generation from User Interface Prototypes

Authors
Castro, JP; Campos, JC;

Publication
2025 INTERNATIONAL CONFERENCE ON GRAPHICS AND INTERACTION, ICGI

Abstract
User-centred design is an iterative process that involves ideation, testing, and refinement to enhance usability, functionality, and overall user experience. However, there is still a need to code the final design. This transition from design to implementation is a time-consuming task. In this paper, we propose an approach and its supporting tool to generate a web application's front-end code from a prototype of its user interface. Our goal is to generate code that can be easily integrated into the overall application development. The results demonstrate that the proposed tool can achieve visual fidelity comparable to that of existing commercial plugins, while producing higher-quality code that better reflects the behaviour specified in the prototype.

On the Role of Generative AI in Explaining Model Checking Counterexamples

Authors
Moreira, EJVF; Campos, JC;

Publication
ENGINEERING INTERACTIVE COMPUTER SYSTEMS: EICS 2024 INTERNATIONAL WORKSHOPS

Abstract
Formal verification can be a complementary approach to UCD, offering a systematic and repeatable process to address the demands of designing safety and mission-critical interactive systems. However, the practical application of formal verification often encounters barriers to accessibility for non-technical stakeholders. In the case of model checking, although the verification step is fully automated, developing the required specifications and interpreting the verification results requires considerable technical expertise in formal methods. Recent developments in generative Artificial Intelligence (AI) have driven proposals for Large Language Models (LLMs) to be applied throughout various phases of software engineering. This begs the question of whether LLMs might be used to help bridge the gap between formal techniques and tools and stakeholders lacking technical expertise. This paper explores how these questions might be addressed in the context of an ongoing effort aimed at translating model-checking counter-examples into natural language explanations, making them accessible to designers and domain experts.

Engineering Interactive Systems Embedding AI Technologies (3rd workshop on)

Publication
COMPANION OF THE 2025 ACM SIGCHI SYMPOSIUM ON ENGINEERING INTERACTIVE COMPUTING SYSTEMS, EICS 2025 COMPANION

Abstract
This workshop proposal is the third edition of a workshop which has been organised at EICS 2023 and EICS 2024. This edition aims to bring together researchers and practitioners interested in the engineering of interactive systems that embed AI technologies (as for instance, AI-based recommender systems) or that use AI during the engineering lifecycle. The overall objective is to identify (from experience reported by participants) methods, techniques, and tools to support the use and inclusion of AI technologies throughout the engineering lifecycle for interactive systems. A specific focus is on guaranteeing that user-relevant properties such as usability and user experience are accounted for. Contributions are also expected to address system-related properties, including resilience, dependability, reliability, or performance. Another focus is on the identification and definition of software architectures supporting this integration.
