A novel policy-driven reversible anonymisation scheme for XML-based services
Ulltveit-Moe, Nils; Oleshchuk, Vladimir (Journal article; Peer reviewed, 2014)This paper proposes a reversible anonymisation scheme for XML messages that supports fine-grained enforcement of XACML-based privacy policies. Reversible anonymisation means that information in XML messages is anonymised, ... -
A roadmap towards improving managed security services from a privacy perspective
Ulltveit-Moe, Nils (Journal article; Peer reviewed, 2014)This paper proposes a roadmap for how privacy leakages from outsourced managed security services using intrusion detection systems can be controlled. The paper first analyses the risk of leaking private or confidential ... -
Decision-cache based XACML authorisation and anonymisation for XML documents
Ulltveit-Moe, Nils; Oleshchuk, Vladimir A (Journal article; Peer reviewed, 2012)This paper describes a decision cache for the eXtensible Access Control Markup Language (XACML) that supports fine-grained authorisation and anonymisation of XML based messages and documents down to XML attribute and element ... -
Location-Aware Mobile Intrusion Detection with Enhanced Privacy in a 5G Context
Ulltveit-Moe, Nils; Oleshchuk, Vladimir A; Køien, Geir M. (Journal article; Peer reviewed, 2010)The paper proposes a location-aware mobile Intrusion Prevention System (mIPS) architecture with enhanced privacy that is integrated in Managed Security Service (MSS). The solution is envisaged in a future fifth generation ... -
Mobile security with location-aware role-based access control
Ulltveit-Moe, Nils; Oleshchuk, Vladimir A (Lecture Notes of the Institute for Computer Sciences, Social Informatics and Telecommunications Engineering;94, Chapter; Peer reviewed, 2012)This paper describes how location-aware Role-Based Access Control (RBAC) can be implemented on top of the Geographically eXtensible Access Control Markup Language (GeoXACML). It furthermore sketches how spatial separation ... -
Optimal Utilization of Charging Resources of Fast Charging Station with Opportunistic Electric Vehicle Users
Konara, Konara Mudiyanselage Sandun Y.; Kolhe, Mohan Lal; Ulltveit-Moe, Nils; Balapuwaduge, Indika A.M. (Peer reviewed; Journal article, 2023)The key challenge with the rapid proliferation of electric vehicles (EVs) is to optimally manage the available energy charging resources at EV fast-charging stations (FCSs). Furthermore, the rapid deployment of fast-charging ... -
Privacy Violation Classification of Snort Ruleset
Ulltveit-Moe, Nils; Oleshchuk, Vladimir A. (Journal article; Peer reviewed, 2010)It is important to analyse the privacy impact of Intrusion Detection System (IDS) rules, in order to understand and quantify the privacy-invasiveness of network monitoring services. The objective in this paper is to classify ... -
Privacy-enhanced network monitoring
Ulltveit-Moe, Nils (Doctoral dissertations at the University of Agder;83, Doctoral thesis; Peer reviewed, 2013)This PhD dissertation investigates two necessary means that are required for building privacy-enhanced network monitoring systems: a policy-based privacy or confidentiality enforcement technology; and metrics measuring ... -
Reliability Enhancement of Fast Charging Station under Electric Vehicle Supply Equipment Failures and Repairs
Konara, Konara Mudiyanselage Sandun Y.; Kolhe, Mohan Lal; Ulltveit-Moe, Nils; Balapuwaduge, Indika A.M. (Peer reviewed; Journal article, 2023)This work focuses on the enhancement of the charging reliability of both scheduled (SEVs) and opportunistic (UEVs) electric vehicle (EV) users in an EV fast charging station (FCS). The proposed charging coordination ... -
Techno-Economic Performance Evaluation of Photovoltaic based Micro-Grid with Energy Management Strategies
Sharma, Arvind (Doctoral Dissertations at the University of Agder; no. 313, Doctoral thesis, 2021)The operational performance of grid connected micro-grid system can be affected by many factors e.g. techno-economic sizing, appropriate energy management strategy, geographical locations, grid constrains and electricity ...
