Security and efficient data dissemination over wireless sensor network with raptor codes

Security and efficient data dissemination over wireless network has been the focus of research in academic, military and commercial domains for many years. Unfortunately, proposed security solutions for data dissemination over wireless network are not efficient enough. In this work, a novel security and efficient data dissemination scheme which integrates authentication into a SE-Raptor (security enhanced Raptor) codes is investigated. In SE-Raptor codes, encoding packets with degree one are encoded again, and many promiscuous packets are took part in encoding. Simulation results show that the proposed method has better performance in terms of encoding ratio, degree ratio, encoding and decoding efficiency. Additionally, our analysis shows that data confidentiality, bogus data protection and deny of service properties are provided by the proposed scheme.
