Secured Distributed IoT Based Supply Chain Architecture

The main goal of the Internet of Things (IoT) in supply chains is to provide accurate and real-time tracking of items. But, in modern business management, new perspectives are opened and new tasks are invented. In this network involving a myriad of businesses and relationships, the supply chain management (SCM) process should assure global interoperability between trading entities and partners. The traditional technologies are still unable to offer a cost efficient and trusted system for information sharing and provenance recording between these entities and partners having different clearance and priorities. Therefore, security and scalability become an important consideration for the design of supply chain architecture (SCA). In 1979, Ralph Merkle has proposed the Merkle tree which is a key management scheme based on tree architecture. In this paper, we present a secured distributed supply chain architecture based on Merkle tree. The proposed design aims at replacing the current Peer to Peer architecture using a scalable and secure key management scheme.
