A network reprogramming protocol is made for updating the firmware of a Wireless Sensor Network (WSN) in situ. For security reasons, every firmware update must be authenticated to prevent an attacker from installing its code in the network. While existing schemes can provide authentication services, they are insufficient for a new generation of network coding-based reprogramming protocols like Rateless Deluge. The authors propose Secure Rateless Deluge or Sreluge, a secure version of Rateless Deluge that is resistant to pollution attacks (denial-of-service attacks aimed at polluting encoded packets).
