Vanesa Daza, Roberto Di Pietro, Flavio Lombardi and Matteo Signorini recieved the Best Paper Award at the EUSPN-2017.

The 8th International Conference on Emerging Ubiquitous Systems and Pervasive Networks (EUSPN-2017) is a leading international conference for researchers and industry practitioners to share their new ideas, original research results and practical development experiences from all Ubiquitous Systems and Pervasive Networks related areas. The EUSPN-2017  was held in Lund, Sweden on September 18-20, 2017. 


With a paper entitled "CoLLIDE: CLoud Latency-based IDEntification", Vanessa Daza, Roberto DiPietro, Flavio Lombardi and Matteo Signorini, received the Best Paper Award.  



As services steadily migrate to the Cloud, the availability of an overarching identity framework has become a stringent need. Moreover, such an identity framework is now critical in the Internet of Things. To address this problem, identification solutions have been proposed in the past leveraging software or hardware properties of devices. While those solutions proved feasible, their root of trust was based either within the device or in a remote server.

In this paper, we overcome the above paradigm and start investigating novel perspectives offered by an overarching identity framework that is not based on client/server properties, but on the network latency of their communications. The core idea behind our approach is to leverage cloud client/server interactions’ latency patterns over the network to derive unique and unpredictable identity factors. Such factors can be used to design and implement effective identification schemes especially suitable for cloud-based services. To the best of our knowledge, our approach is the first one ensuring unclonability and unpredictability properties, relying on neither trusted computing bases (TCBs) nor on classical pseudo-random number generators (PRNGs). The experimental tests presented in this paper, conducted on worst case conditions, show that the network latency (generated between two interacting devices) can produce random values with properties close to the ones generated by most of the well-known PRNGs, that are an ideal fit for providing unique identifiers.
