Many IoT devices lack memory and computational complexities of modern computing devices, making them vulnerable to a wide range of cyber attacks. Among these, DDoS attacks are a growing concern in IoT. Such attacks are executed through the introduction of rogue devices and then using them and/or other compromised devices to facilitate DDoS attacks by generating relentless traffic. This paper aims to address DDoS security issues in IoT by proposing an integration of IoT devices with blockchain. This paper uses Ethereum, a blockchain variant, with smart contracts to replace the traditional centralized IoT infrastructure with a decentralized one. IoT devices are then required to access the network using smart contracts. The integration of IoT with Ethereum not only prevents rogue devices from gaining access to the server but also addresses DDoS attacks by using static resource allocation for devices.
