BlockCom: Blockchain-based efficient communication and storage protocol

Smart application has been focused more to solve real-world problems like smart home, smart street lighting system etc., but the concept of data transmission between devices require precise attention to preserve security with better performance output in device communication. The blockchain is a decentralized computation and information sharing platform to enable different players to verify on the fly. This paper presents a hyper-ledger fabric-based blockchain architecture using a one-way hash function to employ distributed data storage, to enhance the security of the smart applications, and to improve performance in the computation. The proposed protocol resists to different attacks, i.e., modification, impersonation, replay, man-in-the-middle, stolen verifies, device injection, false reputation, and appending. Moreover, performance results are comparatively better rather than relevant vehicular communication protocols.
