However, reliable delegated user authentication and authorization also pose organizational challenges regarding the quality management of user data. Level of Assurance (LoA) concepts have been adapted and applied to IFs, but their inhomogeneous proliferation bears the risk of aggravating instead of simplifying the manual work steps. This is increased by the providing IT services for multiple or dynamically set up IFs. This article presents a novel LoA management approach that has been designed for a high degree of automation, adopts the approach for the dynamic metadata exchange by G\u00c9ANT-TrustBroker and exemplifies its usage.<\/jats:p>","DOI":"10.1515\/pik-2016-0003","type":"journal-article","created":{"date-parts":[[2017,6,7]],"date-time":"2017-06-07T10:02:20Z","timestamp":1496829740000},"source":"Crossref","is-referenced-by-count":0,"title":["Level of Assurance Management Automation for Dynamic Identity Federations based on Vectors of Trust"],"prefix":"10.1515","volume":"39","author":[{"given":"Wolfgang","family":"Hommel","sequence":"first","affiliation":[]},{"given":"Michael","family":"Grabatin","sequence":"additional","affiliation":[]},{"given":"Stefan","family":"Metzger","sequence":"additional","affiliation":[]},{"given":"Daniela","family":"P\u00f6hn","sequence":"additional","affiliation":[]}],"member":"374","reference":[{"key":"ref201","article-title":"Degrees of reliance https www aai dfn de en der dienst degrees of reliance retrieved th","volume":"17","author":"DFNb","year":"2016","journal-title":"Online"},{"key":"ref41","first-page":"32014","article-title":"European Parliament and the Council of the European Union Lex Regulation of the European parliament and of the council EU retrieved th","volume":"14","author":"December","year":"2014","journal-title":"Eur EUR Online"},{"key":"ref71","first-page":"1","article-title":"Identity Assurance Profiles Bronze Version","volume":"13","author":"InCommon","year":"2013"},{"key":"ref241","first-page":"1","article-title":"Identity Assurance Profiles Bronze Version","volume":"13","author":"InCommon","year":"2013"},{"key":"ref91","article-title":"Initiative Identity Assurance Framework http kantarainitiative org confluence display LC Identity Assurance Framework retrieved th","volume":"17","author":"Kan Kantara","year":"2016","journal-title":"Online"},{"key":"ref211","first-page":"32014","article-title":"European Parliament and the Council of the European Union Lex Regulation of the European parliament and of the council EU retrieved th","volume":"14","author":"December","year":"2014","journal-title":"Eur EUR Online"},{"key":"ref141","article-title":"https www sunet se swamid policy retrieved th","volume":"17","author":"Sun Sunet","year":"2016","journal-title":"Online"},{"key":"ref121","article-title":"Rechenzentrum der Universit\u00e4t W\u00fcrzburg StudiSoft Webshop http www studisoft de retrieved th","volume":"17","author":"August","year":"2016","journal-title":"Online"},{"key":"ref261","article-title":"Initiative Identity Assurance Framework http kantarainitiative org confluence display LC Identity Assurance Framework retrieved th","volume":"17","author":"Kan Kantara","year":"2016","journal-title":"Online"},{"key":"ref51","article-title":"eduGAIN Service Homepage http services geant net edugain Pages Home aspx retrieved th","volume":"17","author":"G\u00c9ANT","year":"2016","journal-title":"Online"},{"key":"ref311","article-title":"https www sunet se swamid policy retrieved th","volume":"17","author":"Sun Sunet","year":"2016","journal-title":"Online"},{"key":"ref221","article-title":"eduGAIN Service Homepage http services geant net edugain Pages Home aspx retrieved th","volume":"17","author":"G\u00c9ANT","year":"2016","journal-title":"Online"},{"key":"ref251","first-page":"29115","article-title":"ISO ISO ISO Entity authentication assurance framework Standard ISO","volume":"13","year":"2013","journal-title":"International"},{"key":"ref291","article-title":"Rechenzentrum der Universit\u00e4t W\u00fcrzburg StudiSoft Webshop http www studisoft de retrieved th","volume":"17","author":"August","year":"2016","journal-title":"Online"},{"key":"ref31","article-title":"Degrees of reliance https www aai dfn de en der dienst degrees of reliance retrieved th","volume":"17","author":"DFNb","year":"2016","journal-title":"Online"},{"key":"ref191","article-title":"Authentication authorization infrastructure https www aai dfn de en retrieved th","volume":"17","author":"DFNa","year":"2016","journal-title":"Online"},{"key":"ref81","first-page":"29115","article-title":"ISO ISO ISO Entity authentication assurance framework Standard ISO","volume":"13","year":"2013","journal-title":"International"},{"key":"ref21","article-title":"Authentication authorization infrastructure https www aai dfn de en retrieved th","volume":"17","author":"DFNa","year":"2016","journal-title":"Online"}],"container-title":["PIK -
