Blockchain-based Digital Identity for Secure Authentication of IoT Devices In 5G Networks

The growing use of IoT in 5G networks has led to new security concerns, particularly related to the lack of authentication mechanisms. This paper proposes a new way to solve this problem by using blockchain-based digital tokens to identify IoT devices and enable secure communication over 5G networks, etc. Our Digital Identity Authentication using Blockchain (DIA-Be) approach proposed in this paper is to create a unique blockchain- based digital identity for each device. The created digital identities are verified using cryptographic protocols and stored in a tamper- proof decentralized ledger. These digital identities can be used to authenticate devices as they connect to a network, preventing unauthorized access, and allowing secure communication channels to be established. We discuss the benefits of this approach, including improved security, reliability, and deployment, and highlight some of the challenges that must be addressed when implementing this approach. Our plan shows our commitment to improving the security of IoT devices in 5G networks, with the ability to create safe and secure IoT devices that can share communications with each other without a network.
