Securing Topology Control in SDWSNs Using Identity-Based Cryptography

In software-defined wireless sensor networks (SDWSNs), topology control is a fundamental procedure to maintain the global network topology. However, open channels of SDWSNs make it possible for an attacker eavesdrop, replay, or modify messages, thus posing great threat operations. The security SDWSN has not received enough attention yet. Identity-based cryptography (IBC) may be fitter due its capability generating public key from node identity directly, compared with traditional cryptography. particular, identity-based combined encryption and signature (IBCES) could encrypt sign messages using same identity. As such, secure confidentiality, integrity, authentication information, we put forward mechanism based on IBCES. First, use authenticated agreement scheme implement neighbor nodes hop-to-hop verification via discovery processes. Then through admission establishment process, end-to-end are established between nodes, sinks, Controller. Finally, collection management processes supporting flat hierarchical structures designed guarantee information. Theoretical analysis shows that our methods satisfy needs resist several attacks. experimental results indicate mechanisms suitable SDWSNs.
