Recent studies have demonstrated that it is possible to perform public key cryptographic operations on the resource-constrained sensor platforms. However, the significant resource consumption imposed by public key cryptographic operations makes such mechanisms easy targets of Denial- of Service (DoS) attacks. For example, if digital signatures such as ECDSA are used directly for broadcast authentication without further protection, an attacker can simply broadcast forged packets and force the receiving nodes to perform a large number of unnecessary signature verifications, eventually exhausting their battery power. This paper studies how to deal with such DoS attacks when signatures are used for broadcast authentication in sensor networks. In particular, this paper presents two filtering techniques, a group-based filter and a key chain-based filter, to handle DoS attacks against signature verification. Both methods can significantly reduce the number of unnecessary signature verifications that a sensor node has to perform. The analytical results also show that these two techniques are efficient and effective for resource-constrained sensor networks.
