Broadcast authentication is an important process that is used to secure the applications from different kinds of attacks including Denial of service (DoS) attacks. Timed Efficient Stream Loss-tolerant Authentication (TESLA) and Digital Signature are used in Wireless Sensor Networks (WSNs) to provide broadcast authentication, but both are vulnerable to DoS attacks; attackers keep broadcasting forged messages which will cause extra cost on the network due to the power consumption. This will exhaust the node’s energy, which consequently reduces the network’s lifetime. In this paper we first present related schemes that are trying to defend against or contain such DoS attacks. Secondly, we propose a new scheme that allows the receiver sensor node to recognize forged message before verifying its authenticity in order to avoid performing many unnecessary operations and so preventing DoS from damaging the availability of the network and additionally reducing the delay that is resulted from the verification itself. The proposed scheme protects nodes by using adaptive window after passing a weak pre-authenticator test. A security analysis for the propose scheme is presented at the end of the paper.
