A Trust-Based Strategy for Addressing Residual Attacks in the RELOAD Architecture

Telephony over IP has undergone a large-scale deployment thanks to the development of high-speed broadband access and the standardization of signalling protocols. A particular attention is currently given to P2PSIP networks which are exposed to many security threats. The RELOAD protocol defines a peer-to-peer signalling overlay designed to support these networks. It introduces a security framework based on certification mechanisms, but P2PSIP networks are still exposed to residual attacks, such as refusals of service. The authors propose in this work to address these residual attacks by integrating into the RELOAD architecture a dedicated trust model coupled with prevention countermeasures.
