An Analysis of Broadcast Authentication and Security Schemes in Wireless Sensor Networks

Wireless Sensor Networks (WSNs) are susceptible to various attacks as they are placed in hostile environments. Several security and authentication mechanisms are proposed for in terms of key exchange mechanisms, handshake protocols, and other routing protocols. The proposed triple key based broadcast authentication protocol is compared with the several other existing security schemes in WSN. The proposed triple key based broadcast authentication scheme works upon TESLA (Timed Efficient Stream Loss-tolerant Authentication) protocol and ECDH (Elliptic Curve Diffie-Hellman) key agreement scheme. The proposed WSN authentication performs better compared to other security schemes, in terms of accuracy, detection of attacks, resiliency, memory consumption, nodal detection, and average of total transmission energy consumed per node.
