Abstract

The market size of Internet of things (IoT) has grown rapidly in recent years. 
As a result, plenty of promising IoT applications have attracted lots of 
interest from both industry and academic. Unfortunately, Current IoT devices 
are suffer from the privacy and security issues. Thus, blockchain has been used 
to tackle the challenge. However, current blockchain design cannot meet the 
requirement of IoT.

In this thesis, we focus on the blockchain design for IoT considering following 
aspects:

Performance: We propose a reputation-based sharding blockchain to improve the 
performance of the blockchain for IoT.

Privacy: We propose a new privacy-preserving enhancement scheme for 
reputation-based blockchain to defend against slowly adaptive attacker.

Authenticity: We propose an adversarial attack on the data integrity and two 
authentication systems to protect the data authenticity before recoding them on 
the blockchain.

Application: We propose a new layer-2 design for supply chain that can reduce 
the collateral requirement.
