The primary goal of photonics is to use light to perform functions that fall within the domains of telecommunications, sensing, information processing, and the like. The research activity at DEI touches the following main topics:

The SIGNET research group addresses several challenges in the broad domain of signal processing and wireless networking, with emphasis on the design of communication protocols, edge computing, sensing, and the analysis of complex networks.

Our group has a decade long expertise on the security in wireless communications and networks, as well as in information theoretic based unconditional security, employing physical layer methods, and with a special focus on message authentication.

More recently, we have devoted a significant activity to the authentication and integrity protection of global navigation satellite systems (GNSS) with both receiver and system side solutions against jamming and spoofing attacks.

An active area of research is digital communications, with an emphasis on new cellular systems. Expertises include topics of
