In this paper we present SECTOR, a set of mechanisms for the secure verification of the time of encounters between nodes in multi-hop wireless networks. This information can be u...
ct This paper proposes a Secure Encrypted-data Aggregation (SEA) scheme in mobile wireless sensor networks (MWSN) environment. Our design for data aggregation eliminates redundant ...
In this paper, we present a secure group key management scheme for hierarchical mobile ad-hoc networks. Our approach aims to improve both scalability and survivability of group ke...
Abstract. For ubiquitous communication self-organising adhoc networks become more and more important. We consider mobile phones as appropriate secure gateways to provide access to ...
In this paper we present a context-sensitive security model for privacy protection on mobile phones. We describe the system TreasurePhone which implements this security model. The...
