RFID Based Verifiable Ownership Transfer Protocol Using Blockchain Technology

摘要

Most of the existing RFID based ownership transfer protocols are in need of TTP or require reader to reader communication in a centralized system. In the post supply chain, the products are to be tracked to prove their originality in a distributed environment. This paper aims to provide a verifiable ownership transfer of products attached with an RFID tag using blockchain technology to address various security requirements. The proposed protocol consists of two phases; in the first phase the buyer commits to buy the product and in the second phase actual ownership is transferred from the seller to the buyer. Analysis of the proposed protocol is carried out and it shows that our protocol is relatively better than the existing related schemes with respect to security requirements.
