Offline Authentication Scheme based on Blockchain Technology for Smart Lock

Driven by the technology of mobile Internet of things and the wide demand of sharing economy, the development of smart locks is changing with each passing day. Current schemes rely on the open network architecture which has security vulnerabilities, privacy leaks, vulnerability to various attacks and other security risks. We propose an end-to-end succinct non-interactive offline authentication scheme based on blockchain technology(BC-SNOA). Using blockchain techniques such as anonymity, ellipticcurve cryptography, workload consensus, and privacy-preserving zero-knowledge proof, the BC-SNOA implements one-time pad to improve confidentiality, offline authentication to avoid network remote intrusions and the risk of network services interruptions. It is difficult to replicate and crack because of the in chip calculation of workloads and mathematical problems. Compared with current smart locks which extract biometric verification information and control by network services, the BC-SNOA scheme is likely to accomplish beneficial properties such as high verification performance and more secure, and also makes simple hardware implementations possible.
