Diana Gratiela Berbecaru works in the Department of Control and Computer Engineering - DAUIN at Politecnico di Torino, where she is currently an Assistant Professor with time contract. She is a member of the Computer and Network Security Group (TORSEC).
Diana holds a Ph.D. in Computer Science from Politecnico di Torino, Italy, and an M.Sc. in Systems and Computer Science from the University of Craiova, Romania. She is an alumnus of ``Colegiul National Carol I Craiova''.
​
Her research interests lie in computer and network security. In particular, she studied distributed systems exploiting Public Key Infrastructures (PKIs), and the X.509 certificate validation process. She evaluated network security protocols, such as TLS (Transport Layer Security), studying its robustness as well as its performance in different application contexts. She studied optimizations of some protocols, such as the OCSP (Online Certificate Status Protocol) for certificate validation in wireless and sensor networks (Internet of Things). She evaluated some advanced formats of signatures, e.g. forward secure signature schemes and one-time signatures. She studied the Merkle Hash Trees and applied them in various applications. She proposed a location-based authentication method by exploiting GNSS receivers and certified location data. In recent years, her research focused also on electronic identity, user authentication and authorization, network forensics, and the Pan-European eIDAS Network implementing the European eIDAS Regulation 910/2014 on electronic identification and trust services.
​
Since 2005, she is acting as Adjunct Professor at Politecnico di Torino (Italy) for the courses on computer security. She acts as a reviewer in several international top-quality journals, such as IEEE Access, Sensors (MDPI), and Elsevier’s Journal of Network and Computer Applications. Diana Berbecaru published more than 40 scientific papers related to computer security, some of them in top journals, such as IEEE Access, Software: Practice and Experience (Wiley), and IEEE/ACM Transactions on Networking. She acts as Associate Editor for IEEE Access journal.
