Timed Efficient Stream Loss-tolerant Authentication (TESLA) and digital signature are security implementations of broadcast authentication in Wireless Sensor Networks (WSNs). Both approaches, however, are considered vulnerable to DoS attacks. Encountering this attack requires a scheme that addresses two security measures: prevention and detection. This paper provides a hybrid solution between prevention and detention scheme. The prevention part is based on the dynamic window scheme installed at each sensor node. The detection part adopts the Fuzzy Logic Intrusion Detection Scheme (FL-IDS) installed at monitor nodes.
