The Session Initiation Protocol (SIP) is a signaling protocol for the creation, modification and termination of multimedia sessions with one or more participants. While SIP operates in highly dynamic environments such as Next Generation Networks, in current deployments its access control support is based on traditional access control models. The main problem these models face is that under certain circumstances they tend to be inadequate in current highly dynamic environments. Usage Control is an access control model that supports the same functionalities as traditional models do, but further introduce novel ones. In a previous work, an architecture supporting continuous authorization on SIP based on the Usage Control model was presented. Here this architecture is further elaborated, described in more detail and experimentally evaluated.

Abstract
The Session Initiation Protocol (SIP) is a signaling protocol for the creation, modification and termination of multimedia sessions with one or more participants. While SIP operates in highly dynamic environments such as Next Generation Networks, in current deployments its access control support is based on traditional access control models. The main problem these models face is that under certain circumstances they tend to be inadequate in current highly dynamic environments. Usage Control is an access control model that supports the same functionalities as traditional models do, but further introduce novel ones. In a previous work, an architecture supporting continuous authorization on SIP based on the Usage Control model was presented. Here this architecture is further elaborated, described in more detail and experimentally evaluated.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
