Low-Earth-Orbit satellite access network (LEO-SAN) can realize real-time and three-dimensional broadband on the earth anywhere any time. It has become a major development trend of Internet mobile communication networks, attracted more attention research from academia industry. LEO satellites achieve global coverage through giant constellations. Compared with medium- high-orbit satellites, have ...

The Access Node Control Protocol (ANCP) aims to communicate Quality of Service (QoS)-related, service-related, and subscriber-related configurations and operations between a Network Access Server (NAS) and an Access Node (e.g., a Digital Subscriber Line Access Multiplexer (DSLAM)). The main goal of this protocol is to allow the NAS to configure, manage, and control access equipment, including t...

Currently there are no Internet access authentication protocols available that are lightweight, can be carried over arbitrary access networks, and are flexible enough to be used in all the likely future ubiquitous mobility access contexts. This article proposes the PANA/GSM authentication protocol for heterogeneous network access as a step towards filling this gap. A security analysis of the PA...

With the apparition of accurate security monitoring tools, the gathered alerts are requiring operators to take action to prevent damage from attackers. Intrusion prevention currently provides isolated response mechanisms that may take a local action upon an attack. While this approach has been taken to enhance the security of particular network access control points, it does not constitute a co...
