Self-Describing Delegation Networks for the Web

L. Kagal, T. Berners-Lee, D. Connolly, D. Weitzner
Seventh IEEE International Workshop on Policies for Distributed Systems and Networks (POLICY'06)  
Rein provides ontologies for describing policy and delegation networks, and provides mechanisms for reasoning over them, both of which can be used to develop domain and policy language specific access  ...  We propose Rein -a policy and delegation framework that is grounded in Semantic Web technologies -to help the Web preserve maximum expressiveness for local policy communities by enabling global interoperability  ...  Acknowledgements This work is sponsored by the National Science Foundation Awards 0427275 and 0524481.  ...

Minimizing the Network Distance in Distributed Web Crawling [chapter]

Odysseas Papapetrou, George Samaras
2004 Lecture Notes in Computer Science  
In this work we describe IPMicra, a distributed location aware web crawler that utilizes an IP address hierarchy and allows crawling of links in a near optimal location aware manner.  ...  However, the distributed nature of current distributed crawlers is currently not fully utilized. The optimal benefits of this approach are usually limited to the sites hosting the crawler.  ...  We designed and built an efficient self-maintaining algorithm for domain delegation (not just a URL) with minimal network overhead by utilizing information collected from the Regional Internet Registries  ...

Who's Taming Who? Tensions Between People and Technologies in Cyberspace Communities [chapter]

Terrie Lynn Thompson
2011 Exploring the Theory, Pedagogy and Practice of Networked Learning  
This paper draws on conceptual and analytical tools from Actor Network Theory (ANT) to explore how the interactions between web-technologies and self-employed workers shape work-learning practices in an  ...  Community can describe a gathering of people online that is self-managed, organic, driven by a shared interest, and highly social.  ...  These self-employed workers and the web-technologies-inuse are not two separate bundles, but rather co-constituted in the work-learning practices described.  ...

A Self-Organized Mechanism for Thwarting Malicious Access in Ad Hoc Networks

Natalia Castro Fernandes, Marc Moreira, Otto Carlos Muniz Bandeira Duarte
2010 2010 Proceedings IEEE INFOCOM  
This paper introduces a self-organized mechanism to control user access in ad hoc networks without requiring any infrastructure or a central administration entity.  ...  The performance improvement arises mostly from the controller sets autonomy to recover after network partitions.  ...  In ACACIA, the self-adaptation of the parameters to network conditions and the self-management of the controller nodes favor both initialization and network partitions and still guarantee security.  ...

SoK: Delegation and Revocation, the Missing Links in the Web's Chain of Trust [article]

Laurent Chuat, AbdelRahman Abdou, Ralf Sasse, Christoph Sprenger, David Basin, Adrian Perrig
2020 arXiv   pre-print
We analyze solutions that address the long-standing delegation and revocation shortcomings of the web PKI, with a focus on approaches that directly affect the chain of trust (i.e., the X.509 certification  ...  For this purpose, we propose a 19-criteria framework for characterizing revocation and delegation schemes.  ...  Delegation to CDNs Content delivery networks (CDNs) pose new challenges for the web PKI, as they fundamentally alter the trust model upon which HTTPS relies [29] .  ...
