Access systems verify and validate accesses made by users to different resources according to some rules. Access systems can be implemented using IT infrastructure. A classical implementation refers to door access in large buildings. Such a system controls and validates the access in the rooms of a building (such as a company, an institution) according to some policies or access rights. This paper...
An access control system has the role to verify and mediate attempts made by users to access resources in a system. An access control system maps activities and resources to legitimate users. This paper presents a distributed smart card based access control system for a building. The system is Internet centered. Each door has a control access point and all these are connected to a server which will...
In this paper we propose a dynamically invoked service based access control (SBAC) model to efficiently deal with the distributed denial of service (DDoS) attacks. The main idea of the SBAC is based on the observation that if the routers have information about the services that are running on the end host and can identify the upper layer traffic from the IP packet payload, then it becomes easy to...
Secure private networking over the Internet is difficult especially when trying to form a new network with private servers and hosts that belong to different administrative domains. Although such form of private network is useful as a closed group communication environment, simply applying existing VPN technologies is not sufficient. Not to mention common problems such as NAT and firewall traversal,...
Multicasting has not been widely adopted until now, due to lack of receiver or end user (EU) access control. We have developed the Internet group management protocol with access control (IGMP-AC), an extended version of IGMPv3, which provides EU access control by incorporating the AAA framework into the existing multicast service model. Furthermore, IGMP-AC works as an extensible authentication protocol...
