The emergence of mobile P2P systems is largely due to the evolution of mobile devices into powerful information processing units. The relatively structured context that results from the mapping of mobile patterns of behaviour onto P2P models is however constrained by the vulnerabilities of P2P networks and the inherent limitations of mobile devices. Whilst the implementation of P2P models gives rise...
The importance of mobility in networks is being increased together with its number of users and applications. However, we still do not have broadly accepted solutions for mobility in Internet or other type of networks. In particular, mobility is difficult in heterogeneous networks, where heterogeneity could expand over ownership, administration, technology, and so on. We propose for such heterogeneous...
Truly ad hoc networks where no prior knowledge of participants to each other creates difficulties in providing encryption key management services to the network members. If the network uses Public Key Infrastructure (PKI) then a Certificate Authority (CA) must be available at all times. Using threshold cryptography for the CA requires several members to act as servers and collaborate to provide these...
This paper presents a distributed authentication architecture based on peer-to-peer networking paradigms to minimise the delays in authenticating and authorising mobile nodes roaming across different wireless networks. The fundamental principle is to provide a mechanism to shift elements required for authentication closer to the mobile node's current point of access thus reducing the need for interaction...
