DICTATE: DIstributed CerTification Authority with probabilisTic frEshness for Ad Hoc Networks

Jean-Pierre Hubaux, Jun Luo, Patrick Eugster

Securing ad hoc networks is notoriously challenging, notably due to the lack of an on-line infrastructure. In particular, key management is a problem that has been addressed by many researchers but with limited results. In this paper, we consider the case ...

Mobility Helps Security in Ad Hoc Networks

Jean-Pierre Hubaux, Levente Buttyan, Srdan Capkun

Contrary to the common belief that mobility makes security more difficult to achieve, we show that node mobility can, in fact, be useful to provide security in ad hoc networks. We propose a technique in which security associations between nodes are establi ...

Small Worlds in Security Systems: an Analysis of the PGP Certificate Graph

Jean-Pierre Hubaux, Levente Buttyan, Srdan Capkun

We propose a new approach to securing computer networks. With this approach, we achieve security in a fully self-organized manner; by this we mean that to secure a computer network, a security system does not require any kind of certification authority or ...

The Quest for Security in Mobile Ad Hoc Networks

Jean-Pierre Hubaux, Levente Buttyan, Srdan Capkun

So far, research on mobile ad hoc networks has been focused primarily on routing issues. Security, on the other hand, has been given a lower priority. This paper provides an overview of security problems for mobile ad hoc networks, distinguishing the threa ...
