Security for Mobile Crowd Sensing with Opportunistic Protocols

This project studies security and privacy aspects of Mobile Crowd Sensing applications (MCS). This includes the study, design and development of solutions for:

  • Anonymous communications
  • Security in opportunistic networks
  • Privacy in social applications
  • Private and/or anonymous routing in opportunistic networks
  • Anonymous reputation and rewarding systems
  • Data privacy

Project motivation

Within the context of sensing systems, classical wireless sensor network are being overtaken in some scenarios by a new paradigm known as Mobile Crowd Sensing (MCS) which is based in a multitude of different mobile devices such as smartphones, widely deployed in our society.

The large sensing capacity and flexibility of MCS enables the creation of highly versatile platforms that can replace the traditional sensing infrastructures and allows the emergence of new applications. Unfortunately, there are important problems to be solved that prevent MCS from being nowadays a good sound proposal for real life environments. The most relevant problem relates to its security: privacy, rewarding and incentivation of the participants, and trustworthiness of the sensed data remain as open issues. Recent publications also suggest the need for MCS to incorporate support for opportunistic communications between nodes in order to overcome deployment and scalability problems if only infrastructural communications such as 3G/4G are used. Furthermore, this kind of protocols can be used as a supporting mechanism for crowd based privacy and anonymity solutions.

The overall objective of this project is to investigate and develop a secure MCS platform with opportunistic protocols, meeting the current limitations of its security regarding privacy, rewarding, and information trustworthiness.
