Broadcast communication is a dominant communication pattern in WSN. As a major security concern, the broadcast source authentication is needed to mitigate impersonation of a broadcast source, modifications of its broadcasted data, or depletion of the limited energy of sensors caused by an attacker injecting useless broadcast traffic. Several Broadcast Source Authentication Protocols (BSAPs) wer...

Wireless sensor networks (WSNs) consist of lightweight devices with low cost, low power, and short-ranged wireless communication. The sensors can communicate with each other to form a network. In WSNs, broadcast transmission is widely used along with the maximum usage of wireless networks and their applications. Hence, it has become crucial to authenticate broadcast messages. Key management is ...

Broadcast authentication is a critical security service in wireless sensor networks (WSNs). However, due to resource constrained of sensor nodes, providing an authentication mechanism for broadcast message is difficult. This paper deals with the forwarding scheme for wireless sensor networks aimed at combining low computational complexity and high performance in terms of energy efficiency with ...

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...

Wireless broadcast transmission enables Inter-vehicle or Vehicle-to-Vehicle (V2V) communication among nearby vehicles. This supports latency-critical applications for improved safety and maybe optimized traffic. However, V2V is vulnerable to cyber attacks involving message manipulation. Mechanisms are required ensure both authenticity integrity of data, while maintaining drivers privacy against...

Broadcast authentication is a fundamental security service in distributed sensor networks. A scheme named μTESLA has been proposed for efficient broadcast authentication in such networks. However, μTESLA requires initial distribution of certain information based on unicast between the base station and each sensor node before the actual authentication of broadcast messages. Due to the limited ba...
