01 Distributed Architecture for Intrusion Detection in IoT Networks using Smart Contracts

Abstract

DDoS attacks against distributed networks of IoT devices and applications are increasing. In this scenario,countermeasures must also use distributed security means. This paper proposes a distributed architecture of an intrusion detection system for IoT networks using smart contracts in blockchain. The proposed architecture supports interaction mechanisms between the local controllers using smart contracts to distribute security rules among the different devices on the IoT network. To validate the proposal, this paper presents the assessment of parameters required to ensure an acceptable level of reliability in sharing security rules.
