We are pleased to announce the publication of the scientific paper “DrATC: Dynamic routing Algorithm based on Trust Characteristics”, presented at the prestigious 20th International Workshop on Security and Trust Management (STM 2024).
The research
The paper, developed through the collaboration between Lorenzo Monti of Cubit Innovation Labs and Davide Ferraris of the NICS Lab at the University of Malaga, proposes an innovative dynamic routing algorithm that uses different trust characteristics to determine the most reliable path within a network.
Why it matters
In modern networks, especially in IoT and distributed systems, secure communication is essential. Traditional routing algorithms, such as Dijkstra or BGP, rely on metrics such as distance or latency, but they do not consider whether intermediary nodes can be trusted.
DrATC introduces an innovative approach that considers:
- Direct trust: based on previous interactions with a node
- Indirect trust: based on recommendations from other trusted nodes
- Transitive trust: inferred through chains of trusted nodes
- Dynamic trust: adapted over time according to observed behavior
Practical applications
The algorithm can be applied in several scenarios:
- Industrial IoT sensor networks
- Critical communication systems
- Ad hoc and mesh networks
- Distributed cloud infrastructures
The DUCA project
This research was carried out within the European project HORIZON-MSCA-2021-SE DUCA (Grant Agreement No. 101086308), in which Cubit Innovation Labs collaborates with the University of Malaga on cybersecurity and trust management topics.
