BlockPro: Blockchain based Data Provenance and Integrity for Secure IoT Environments

ABSTRACT

Data provenance and data integrity are among the key concerns in IoT based environments such as smart cities, smart grids, and vehicular networks etc. Many IoT devices suffer from both impersonation and data tampering attacks due to their architectural and computational limitations, which are unable to provide adequate level of security. This paper aims to provide and enforce data provenance and data integrity in IoT environments by using Physical Unclonable Functions (PUFs) and Ethereum, a blockchain variant with smart contracts. PUFs provide unique hardware fingerprints to establish data provenance while Ethereum provides a decentralized digital ledger which is able to withstand data tampering attacks.
