Abstract

The rapid advance of Blockchain has been used for the Internet-of-Things to provide reliable distributed infrastructure and applications without a centralized authority. This paper aims to create a new consensus protocol that can be efficiently and resiliently used for the Internet-of-Things based on the Practical Byzantine Fault Tolerance algorithm (PBFT), which is critical for IoT scalability and reliability. The traditional PBFT algorithm fails to provide two significant features: a) resiliency against denial of service (DoS) attacks, and b) high-throughput to quickly reach final consensus when under attack. This paper analyzes the current implementation of PBFT consensus protocol and proposes a new secure approach for achieving consensus by adding the properties of random hash generation and threshold comparison in order to defend against DoS attacks.
