This paper introduces a new lightweight key exchange (KE) protocol which can be suitably implemented on resource-constrained smart devices to protect the privacy of communications in mobile networks. The most attractive features of this new KE protocol are provable security and lightweight. The security of this new KE protocol is based on the known impossibility of finding the unique values for variables...
The advent of conference mobile call demands the security communication between end users. However, currently there is no efficient secure end-to-end protocol exists for conference mobile call. This slows down the steps of conference communication. In this paper a secure end-to-end protocol for remote conference is designed base on previous experts work, which is one-to-one end-to-end protocol. In...
In this paper, we address a scalable key management protocol for ad hoc networks, this protocol is based on new clustering technique. The network is partitioned into communities or clusters based on affinity relationships between nodes. To ensure trusted communications between nodes we proposed two types of keys generated by each clusterhead. The protocol is adaptive according to the limitation of...
