A Secure Network Coding-enabled approach for a Confidential Cluster-based Routing in Wireless Sensor Networks

International audience—Network Coding is a key strategy for meeting the needs of information technology of the next generation.However, collected and distributed data are only profitable if their confidentiality is guaranteed. Lately, there havebeen numerous approaches that exploit network coding properties to comply confidentiality more effectively. This paperproposes a Secure Network Coding based approach for a confidential multi-hop Routing (SNCR) protocol in wirelesssensor networks which aims to thwart external and internal eavesdroppers and minimize energy dissipation in ahierarchical clustered network using an optimized network coding (NC) scheme. The key idea is to limit the transmissionoperations of the network coding coefficients to a single digit transmission in combination with the coded messages. Ourproposition includes a two-level encoding and a decoding processes. We present a confidentiality investigation of theprotocol with the proposed adversial model.It shows that SNCR ensures confidential transmission of data packets in amulti-hop routing scheme and countermeasures the eavesdropping attack
