“…This is consistent with 3GPP and TISPAN specifications [9] on signaling to provide receiver or end user device capabilities. Hence in a real network, the initial device registration (using for example SIP -Session Initiation Protocol [10]) would contain an SDP (Session Description Protocol [11]) from which the appropriate NC strategy could be deducted.…”

Abstract-The impact of Internet content and IP based television on networks is growing. Video is now ubiquitous in the home and on the street. It demands new approaches to video transmission to meet the growing traffic volume. This paper presents a novel strategy for network coding in video transmission. It uses a variety of coding approaches and adds feedback and device discovery to tailor the coding to the receiver ecosystems and can achieve better overall performance than the non coded versions.

Abstract-Today most home networks are connected to the Internet via Network Address Translation (NAT) devices. NAT is an obstacle for services that should be accessible from the public Internet. Especially applications following the peer-topeer paradigm suffer from the existence of NAT. Various NAT Traversal methods emerged in research and standardization, but none of them can claim to be a general solution working in the heterogeneous environment of today's networks. This paper introduces the Advanced NAT Traversal Service (ANTS), a framework improving the communication of existing and future applications across NAT devices. The core idea of ANTS is to use previously acquired knowledge about NAT behavior and services for setting up new connections. We introduce the architecture of the extensible framework and propose a signaling protocol for the coordination of distributed instances. Finally, we compare the framework to ICE showing that ANTS is not only more flexible, but also faster due to the decoupled connectivity checks.

“…[9] During a testing process [2] carried out by us, we have discovered a scenario in which the user is reachable by the attacker and the latest can trigger the former to generate an INVITE + credentials 1 (directed to any target destination). This allows an attacker to impersonate the user at the Proxy for any call.…”

Abstract:The recent and massive deployment of Voice over IP infrastructures had raised the importance of the VoIP security and more precisely of the underlying signalisation protocol SIP. In this paper, we will present a new attack against the authentication mechanism of SIP. This attack allows to perform toll fraud and call hijacking. We will detail the formal specification method that allowed to detect this vulnerability, highlight a simple usage case and propose a mitigation technique.
