摘要：Wireless Sensor Networks (WSNs) are prone to various security breaches as they are placed in hostile environments. Several security and broadcast authentication mechanisms were proposed for securing the WSN fully via key exchange mechanisms, handshake protocols, and other routing protocols. But these existing schemes cannot detect a variety of attacks and are not competent in terms of detection accuracy, resiliency, memory consumption, and transmission energy. An expedited triple key broadcast authentication scheme is proposed based on TESLA (Timed Efficient Stream Loss-tolerant Authentication) protocol, ECDH (Elliptic Curve Diffie-Hellman) key agreement scheme, and ECDSA (Elliptic Curve Digital Signature Algorithm). The signature verification process is accelerated by releasing few intermediate computation results in the WSN by the sensor nodes. This WSN authentication scheme 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.
