DSBS: A novel dependable secure broadcast stream over lossy and non-synchronized channels

Communication networks need broadcast as a key task. Robust loss-tolerant secure broadcast scheme for lossy channels is solicited for applications from real-time multimedia/data stream to some kind of networks with critical operations such as military tasks and critical resource monitoring. In this paper we propose and prototype a novel loss-tolerance mechanism for lossy channels ensuring authenticity, confidentiality, DoS resistance, efficiency and simplicity. As an experimental implementation we prototype our proposal in a wireless sensor networks to show its efficiency.
