Abstract

Real-time wireless broadcast is envisioned to take an important role in Wireless Sensor Networks (WSNs). For example, routing tree construction, network query, software updates, time synchronization, and network management all rely on broadcast. However, due to the nature of wireless communication in sensor networks, attackers can easily inject malicious data or alter the content of legitimate messages during multi hop forwarding. Authentication of the broadcast messages is an effective approach to countermeasure most of the possible attacks, by which the intended receivers can make sure that the received data is originated from the expected source.
