Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

Both the size, and the interconnectivity of computer networks are increasing tremendously. However, the possibility of an attack compromising the network is also increasing, making network security critical. Strong authentication protocols are needed to restrict network access to only authorised users. Most existing protocols for authentication and network access are based on centralised authentication using one authentication server or certificate authority that is unconditionally trusted Despite the use of strong authentication mechanisms, the process is between the user and a single authentication entity. In these protocols, the decision to authenticate or grant service to users is controlled by this single entity. Centralised authentication protocols suffer certain drawbacks. In this paper, a new protocol Secure Network Access Protocol (SNAP) is proposed SNAP increases network security and availability by distributing the trust between several authentication entities
