AARC: First draft of the Blueprint Architecture for Authentication and Authorisation Infrastructures

On the Effects of Authentication and Authorisation Infrastructures on E-Commerce Environments

Authentication and Authorisation Infrastructures (AAIs) support service providers on the Internet in outsourcing security services. AAIs influence and change the process of e-commerce transactions on multiple points. Changes influence users, service providers, and provider federations likewise. This work analyses the alterations implied by an AAI, comparing various AAI paradigms and traditional...

Pervasive geo-security - a lightweight triple-A approach to securing distributed geo-service infrastructures

Security has recently become a major concern in distributed geo-infrastructures for spatial data provision. Thus, a lightweight approach for securing distributed low-power environments such as geo-sensor networks is needed. The first part of this article presents a survey of current security mechanisms for authentication and authorisation. Based on this survey, a lightweight and scalable token-...

Biometric authentication and authorisation infrastructures

Experiences of Applying Advanced Grid Authorisation Infrastructures

The widespread acceptance and uptake of Grid technology can only be achieved if it can be ensured that the security mechanisms needed to support Grid based collaborations are at least as strong as local security mechanisms. The predominant way in which security is currently addressed in the Grid community is through Public Key Infrastructures (PKI) to support authentication. Whilst PKIs address...

An interoperability system for authentication and authorisation in VANETs

Vehicular ad hoc networks (VANETs) have evolved considerably over the last years, but despite the wide number of potential applications, VANETs also raise a broad range of critical security and privacy challenges. To achieve privacy, VANETs enforce the concepts of authentication and authorisation via public key infrastructures, relying on a large set of regional certification authorities with e...
