Mobile technologies make their headway by offering more flexibility to end-users and improve the productivities. Within the application of ubiquitous access and pervasive communication, security (or privacy) and QoS (Quality of Service) are two critical factors during global mobility, so how to get a smooth and fast handover based on a user privacy protected infrastructure is our focus. Based o...

This document describes an abstract mechanism for delivering root keys from an Extensible Authentication Protocol (EAP) server to another network server that requires the keys for offering security protected services, such as re-authentication, to an EAP peer. The distributed root key can be either a usage-specific root key (USRK), a domain-specific root key (DSRK), or a domain-specific usagesp...

BACKGROUND Changing patterns of work in the hospital setting mean different teams look after the same group of patients over the course of any given day. Shift handovers, or hand/sign-off, can give rise to miscommunication of critical information, a patient safety issue. How can we best prepare new doctors for handover? METHODS This was a qualitative, focus-group study, exploring the views of...

IEEE 802.11 WLANs are widely deployed nowadays. While a mobile device is moving around it may need to execute a handoff that usually requires authentication. This results in a long processing delay and leads to degradation of quality of service to the mobile device. Existing authentication methods such as AAA and IEEE 802.1x mechanisms are unable to accommodate low-latency handoff. In this arti...
