Disruption-tolerant networks (DTNs) provide a promising low-cost solution to transfer data in network environment where the connectivity is sporadic and unpredictable. Many existing methods for opportunistic data forwarding depend on the hypothesis that every node forwards messages regardless of the identities of the senders or receivers, however, the networks based on such methods are fragile under...
Mobile ad-hoc networks (MANETs) are based on cooperative and trust characteristic of mobile nodes. Typically, nodes are both autonomous and self-organized without requiring a central administration or a fixed network infrastructure. Due to their distributed nature, MANETs are very vulnerable to various attacks. To enhance the security of MANETs, it is important to rate the trustworthiness of other...
Due to the unique characteristics of Cyber-Physical Systems (CPS) such as interaction with the physical world, many new research challenges arise. Many CPS applications will be implemented on computing devices using mobile ad hoc networks (MANETs). Before these systems can be used in multifarious environments, the security properties of these networks must be fully understood. Recently, several secure...
VANETs (vehicle ad hoc networks) are highly mobile wireless ad hoc networks targeted to support vehicular safety and other commercial applications. Conventional routing protocols in MANETs (mobile ad hoc networks) are unable to fully address the unique characteristics in vehicular networks. On the other hand, some characteristics in VANETs, like mobility constraints and predicable mobility, can benefit...
An efficient online/offline signcryption scheme based on elliptic curve for MANET is proposed in this paper. The proposed scheme takes lower computation and communication cost, since most of computations are carried out offline and online part is very efficient. It not only provides the security properties of confidentiality, authentication, integrity, forward secrecy of message confidentiality and...
