  • Secure on-demand distance vector route discovery in ad hoc networks  
  • by Panagiotis Papadimitratos — 2005 — In IEEE Sarnoff Symposium, Prinction
  • …Abstract — We address the problem of securing the route discovery in mobile ad hoc networks, proposing a light-weight yet robust routing protocol, the Distance-Vector Secure Routing Protocol (DV-SRP). DV-SRP discovers on-demand multiple routes, which are established across the network, without provi…

  • Secure Ad Hoc Networking  
  • by Panagiotis Papadimitratos
  • …The ad hoc networking technology can enable novel civilian and military applications. However, ad hoc networking protocols are vulnerable to a wide range of attacks. The design of defense mechanisms is a challenging problem, especially in comparison to securing traditional, fixed-infrastructure netw…

  • Protection and Fundamental Vulnerability of GNSS  
  • by Panagiotis Papadimitratos — 2008 — In International Workshop on Satellite and Space Communications (IWSSC
  • …Abstract—An increasing number of mobile applications and services require that devices are aware of their location. Global Navigation Satellite Systems (GNSS) are the predominant enabling technology. But location information provided by commercial GNSS is not secure, unlike what is the usual assumpt…

  • Secure Routing for Mobile Ad Hoc Networks (MC2R)  
  • by Panagiotis Papadimitratos, Zygmunt Haas — 2002 — in SCS Communication Networks and Distributed Systems Modeling and Simulation Conference (CNDS 2002
  • …ns on the underlying trust, network size, and membership. SRP discovers one or more routes whose correctness can be verified from the route "geometry" itself. Route requests propagate verifiably to the sought, trusted destination. Route replies are returned strictly over the reversed route, as accu…

  • A CROSS-LAYER DESIGN APPROACH TO ENHANCE 802.15.4  
  • by Panagiotis Papadimitratos, Amitabh Mishra
  • …The low-power communication in wireless sensor networks can be impacted by severe channel impairments. In this paper, to address this problem and achieve high network goodput, we propose that the medium access control protocol takes into consideration the error performance of the underlying wireless…

  • Report on the “Secure Vehicular Communications: Results and Challenges Ahead ” Workshop  
  • by Panagiotis Papadimitratos, Jean-pierre Hubaux
  • …Switzerland. The event brought together experts, from a variety of organizations, working on vehicular communication systems, security and privacy. The fourteen presentations offered an overview of the latest results and reflected the views of public authorities, academia, and industry. During the o…

  • How to Specify and How to Prove Correctness of Secure Routing Protocols for MANET  
  • by Panagiotis Papadimitratos, Invited Paper — 2006 — In IEEE-CS Third International Conference on BroadBand Communcations, Networks, and Systems
  • …Secure routing protocols for mobile ad hoc networks have been developed recently, yet, it has been unclear what are the properties they achieve, as a formal analysis of these protocols is mostly lacking. In this paper, we are concerned with this problem, how to specify and how to prove the correctne…

  • GNSS-based Positioning: Attacks and Countermeasures  
  • by Panagiotis Papadimitratos, Aleksandar Jovanovic — 2008 — IEEE MILITARY COMMUNICATIONS CONFERENCE (MILCOM)
  • …Increasing numbers of mobile computing devices, user-portable, or embedded in vehicles, cargo containers, or the physical space, need to be aware of their location in order to provide a wide range of commercial services. Most often, mobile devices obtain their own location with the help of Global Na…

  • Securing Mobile Ad Hoc Networks  
  • by Panagiotis Papadimitratos, Zygmunt J. Haas — 2002 — in Handbook of Ad Hoc Wireless Networks, M. Ilyas, Editor. 2002
  • …The vision of nomadic computing with its ubiquitous access has stimulated much interest in the Mobile Ad Hoc Networking (MANET) technology. Those infrastructureless, self-organized networks that either operate autonomously or as an extension to the wired networking infrastructure, are expected to su…

  • Efficient and Adjustable Recipient Anonymity in Mobile Ad Hoc Networks  
  • by Reza Shokri, Amir Nayyeri, Nasser Yazdani, Panagiotis Papadimitratos
  • …The privacy of users of mobile devices has been at stake, with emerging systems based on the mobile ad hoc networking technology raising additional concerns. The establishment of a connection between two nodes could readily reveal information to an eavesdropper. One approach to prevent this is to pr…
