DeepSec 2010: Mobile VoIP Steganography: From Framework to Implementation

Thanks to the DeepSec organisation for making these videos available and let me share the videos on YouTube. Speakers: Rainer Poisel | Marcus Nutzinger, Institute of IT Security Research, St. Polten University of Applied Sciences, Austria The need for steganography has arisen from scenarios that forbid the application of cryptographic algorithms for secure communications. Countries that made secret message exchange a delict are an example for such scenarios. This talk describes the development and implementation of a framework based on a novel layered model for auditive steganography. Focus of this presentation is a description of the implementation for mobile devices which include a version for commodity hardware, e.g. WLAN routers, using the OpenWRT SDK. Further the integration into mobile or satellite phones is discussed. Our approach is based on algorithms that use the analogous representation of the digital cover media, hence making the covert channel more resistant against transmission errors.
