Guarded Authentic Local Area Network GALAN
نویسندگان
چکیده
Das Sicherheitssystem GALAN ergänzt existierende heterogene lokale Netze um einen transparenten link-Schutz. Es ermöglicht die Kommunikation über geschützte und ungeschützte Verbindungen in einem Netzwerk sowie die Kopplung von geschützten und ungeschützten Teilnetzen über eine Sicherheits-Brükke. GALAN umfaßt die Sicherheitsdienste Vertraulichkeit, Datenintegrität, Zugangskontrolle und Authentisierung des Datenursprungs durch eine symmetrische online-Verschlüsselung aller Schicht-2-Nutzdaten (MAC-SDU). Die Sicherheitsbrücken vereinbaren für den Schutz von backbone-Kopplungen authentische session keys. In Verbindung mit einem authentischen Boot-Prozeß ermöglicht GALAN eine chipkartenbasierte Benutzerauthentisierung.

Performance Improvement of Expanded Integrated Local Area Networks (RESEARCH NOTE)
In Local Area Networks (LAN) connected together by bridges, flow control and smooth traffic in the network is very important. However, congestion at bridges can cause intensive loss of received frames. In addition, the received frames are thrown away and have to be retransmitted by the source station, which causes more congestion and massive reduction in the overall network throughput. The netw...
متن کاملThe Role of Urban-Rural Links in the Formation of the Local Network in the Border Areas (Gomishan; Golestan Province)
Background and Amis: Urban-rural links play an important role in the local economy and the livelihoods of the inhabitants of rural settlements so it is imperative to study more closely these links, their performances, their spatial-regional planning, and the "local network" approach in the scale of the district and the rural system. Like an efficient approach, the local network can cause func...

In this paper, a new SDN-based framework is proposedto ne-grained control of 802.11 Wireless LANs. This work describes the benets of programmableAcc...
متن کاملPerceived Effects of Poor Road Transportation Network on Crop Production in Kaiama Local Government Area of Kwara State, North Central Nigeria
This paper examines the effect of the poor road transportation network on crop production in one of the rural agrarian local government of Kwara State, Nigeria. A well-structured interview schedule was conducted to elicit information from 120 crop farmers using a two-stage sampling technique. Findings from the study revealed that the poor road transportation network in their area had led to a r...
متن کاملSolving the local positioning problem using a four-layer artificial neural network
Today, the global positioning systems (GPS) do not work well in buildings and in dense urban areas when there is no lines of sight between the user and their satellites. Hence, the local positioning system (LPS) has been considerably used in recent years. The main purpose of this research is to provide a four-layer artificial neural network based on nonlinear system solver (NLANN) for local pos...
