— There have been many time synchronization protocols proposed for sensor networks. However, the issues related with securing such protocols have not received adequate amount of ...
This paper presents a new password authentication and key-exchange protocol suitable for authenticating users and exchanging keys over an untrusted network. The new protocol resis...
In the analysis of security protocols, the knowledge of attackers is often described in terms of message deducibility and indistinguishability relations. In this paper, we pursue ...
Peer-to-peer (P2P) dissemination systems are vulnerable to attacks that may impede nodes from receiving data in which they are interested. The same properties that lead P2P system...
Hop-by-hop data aggregation is a very important technique for reducing the communication overhead and energy expenditure of sensor nodes during the process of data collection in a...
