--- abstract: 'Highly dynamic computing environments, like ubiquitous and pervasive computing environments, require frequent adaptation of applications. Context is a key to adapt suiting user needs. On the other hand, standard access control trusts users once they have authenticated, despite the fact that they may reach unauthorized contexts. We analyse how taking into account dynamic information like context in the authorization subsystem can improve security, and how this new access control applies to interaction patterns, like messaging or eventing. We experiment and validate our approach using context as an authorization factor for eventing in Web service for device (like UPnP or DPWS), in smart home security.' altloc: - http://ijcsi.org/papers/4-1-24-35.pdf chapter: ~ commentary: ~ commref: ~ confdates: ~ conference: ~ confloc: ~ contact_email: ~ creators_id: [] creators_name: - family: TIGLI given: 'Jean-Yves ' honourific: '' lineage: '' - family: LAVIROTTE given: 'Stephane ' honourific: '' lineage: '' - family: REY given: 'Gaetan ' honourific: '' lineage: '' - family: Hourdin given: 'Vincent ' honourific: '' lineage: '' - family: RIVEILL given: 'Michel ' honourific: '' lineage: '' date: 2009-09 date_type: published datestamp: 2009-11-14 11:32:24 department: ~ dir: disk0/00/00/67/09 edit_lock_since: ~ edit_lock_until: ~ edit_lock_user: ~ editors_id: [] editors_name: [] eprint_status: archive eprintid: 6709 fileinfo: /style/images/fileicons/application_pdf.png;/6709/1/4%2D1%2D24%2D35.pdf full_text_status: public importid: ~ institution: ~ isbn: ~ ispublished: pub issn: ~ item_issues_comment: [] item_issues_count: 0 item_issues_description: [] item_issues_id: [] item_issues_reported_by: [] item_issues_resolved_by: [] item_issues_status: [] item_issues_timestamp: [] item_issues_type: [] keywords: ~ lastmod: 2011-03-11 08:57:32 latitude: ~ longitude: ~ metadata_visibility: show note: ~ number: 1 pagerange: ~ pubdom: TRUE publication: 'J.
