It has been shown that a Security Association (SA) established by strong authentication between a node pair in a Mobile Ad Hoc Network (MANET) should not depend on link connectivity [1]. While stale (long) SAs should be renewed, SA duration should be managed by a security policy and based on a trust model regardless of link intermittence. Both the security policy and the trust model are modules of...
Both SNMP and Netflow have advantages and disadvantages in traffic collect and manage, by study, introduced a new network traffic management combining Netflow based on Hash aggregation with SNMP, use hash aggregation to combine the large number of original Netflow data, achieved the compression store of original traffic data and efficient network system management, make full use of the advantages...
The continuous growth of the users pool of Social Networking web sites such as Face book and My Space, and their incessant augmentation of services and capabilities will in the future, meet and compare in contrast with today's Content distribution Networks (CDN) and Peer-to-Peer File sharing applications such as Kazaa and Bit Torrent, but how can these two main streams applications, that already encounter...
Maintaining security associations (SA) in mobile ad hoc networks (MANET) is challenging due to their intrinsically open, dynamic, and decentralized nature. Bandwidth limitations arising from both the physical characteristics of the wireless medium and the control overhead required to maintain routes in a network with changing topology add another level of difficulty to the problem. While establishing...
A Security Association (SA), established by strong authentication, between a node pair in a Mobile Ad hoc Network (MANET) could be lost when its route is disconnected. In contrast, in good channel conditions and stable topology, routing protocols such as the Optimized Link State Routing (OLSR) do not refresh routes periodically, and in doing so, an SA bound to these routes could become stale and out...
There are some goals of Contract Signing Protocol: confidentiality, non-repudiation and fairness, etc. This paper introduced the compositional analysis and pointed out the limitation that the method is lack of ability in analysis fairness. Backes extended compositional analysis, but this improvement can't used in analysis strong fairness. In this paper, we proposed the concept of predecessor message...
Signature based network intrusion detection systems (NIDSs) often report a massive number of elementary alerts of low-level security-related events which are logically involved in a single multi-stage attack. Since be overwhelmed by these alerts, security administrators almost unable to discover complicated multistage attack in time. It is necessary to develop a real-time system to extracting useful...
