A mobile ad hoc network MANET is a self-organized wireless network where mobile nodes can communicate with each other without the use of any existing network infrastructure or centralized administration. Trust establishment and management are essential for any security framework of MANETs. However, traditional solutions to key management through accessing(More)
A mobile ad hoc network MANET is a collection ofwireless mobile nodes dynamically forming a temporary network without the use of any existing network infrastructure or centralized administration. Trust establishment and management are essential for any security framework of MANETs. Providing key management through accessing trusted authorities or(More)
Abstract—In mobile ad-hoc networks (MANETs), traditionalsecurity solutions are not adequate due to the lack of infrastructureand the absence of centralized administration. In thispaper, a threshold key management scheme for MANETs ispresented. The proposed scheme is implemented using ellipticcurve dlog-based cryptosystem. In this scheme, an off-line(More)
Due to the insecure nature of the wireless media, the dynamically changing topology and lack of infrastructure, security in mobile ad hoc networks is hard to achieve. In this paper we present an analysis of a message-relaying based key distribution scheme for mobile ad hoc networks that was previously proposed by van der Merwe et al. Considering the message(More)
