BSAMS: Blockchain-Based Secure Authentication Scheme in Meteorological Systems

The security of communication between Internet of Things devices is a big concern in this field, and with the increase in the number of devices and users, the current architecture and communication protocols cannot adequately respond to the system's needs, such as authentication and access authorization. One of the important solutions to this problem is using distributed and decentralized networks such as blockchain. So far, various blockchain-based authentication and key agreement protocols have been presented in the Internet of Things and similar environments. However, a secure authentication scheme has not been proposed for meteorological systems.This paper proposes a secure authentication scheme based on the blockchain network for meteorological systems resistant to various attacks. The Security of the proposed project against formal and informal attacks is evaluated, and the analysis results show that Securityrity of the proposed scheme resists active and passive attacks. In the following, the proposed scheme is evaluated in terms of computational costs, and the evaluation results show that the proposed scheme is increasing compared to similar schemes due to the focus on computational security.
