Abstract: With the popularity of internet of things (IoT) devices, distributed denial of service (DDoS) attacks initiated by IoT devices have become ferce. To solve such problems, this paper proposes a detection and defense architecture based on edge computing and blockchain. According to the business characteristics of IoT devices, the suspected DDoS anomaly detection is implemented at edge nodes. Then the DDoS warning is obtained by sharing and analyzing the preliminary results with blockchain. Finally, DDoS connection is fltered at edge nodes based on the reward mechanism. The detection and defense is deployed at the source distributely, which can avoid high cost and network congestion caused by trafc extraction and cleaning, and can prevent the increasement of total DDoS trafc by fltering the trafc continuously at the source when DDoS is detected.

Key words: distributed denial of service (DDoS), share & analysis, blockchain, edge computing, IoT devices
