Instead, the device registration in a server database, ownership of the device, and the authentication credentials for both network access and application-level security are all be established at the time of the device deployment. Compared to all other EAP methods, EAP-NOOB does not require any pre-configured credentials on the device. EAP-NOOB is intended specifically for bootstrapping various IoT devices with limited input and output capabilities. Nimble out-of-band authentication for EAP (EAP-NOOB) is a new EAP method which provides a nimble approach for IoT device bootstrapping. Furthermore, users are often confused when different devices require different processes for initial bootstrapping and device configuration.Д®xtensible authentication protocol (EAP) is an authentication framework that supports numerous methods for authentication. This contradicts the idea of seamless interoperability of the devices in the IoT while also adding costs and complexity to the manufacturing process. IoT device manufacturers currently employ a variety of often proprietary secure bootstrapping techniques for their IoT devices. Secure bootstrapping is the process by which an IoT device gets the necessary configuration information and security credentials to become an operational part of the network and an IoT ecosystem. Therefore, it is important that IoT devices have robust security mechanisms. , the biggest challenges in IoT are presently related to security and privacy protection. Insecure IoT devices may act as gateways for attacks against the entire Internet infrastructure. While IoT provides great benefits and opportunities, there exist severe security risks. Internet connectivity for these devices aims to improve user experience by automating various processes and exchanging information without user involvement. IoT devices include connected cards, machines, instruments, wearables, and other consumer electronics. According to a forecast, by 2022, the amount of Internet connected devices will reach about 29 billion, of which 18 billion will be IoT-related devices.

The number of internet-of-things (IoT) devices is growing rapidly. Using our implementation, we evaluate the usability, security, benefits, and limitations of each of the OOB channels. Thereafter, we implement three OOB channels for EAP-NOOB using near-field communication, quick response codes, and sound. We provide a brief overview of the EAP-NOOB protocol and describe its unique OOB channel requirements. We then look at one candidate bootstrapping protocol: Nimble out-of-band authentication for EAP (EAP-NOOB). We begin this paper by understanding the need for OOB channels and performing a literature survey of existing standards and devices that rely on OOB channels.

Therefore, several device bootstrapping protocols rely on an out-of-band (OOB) channel for initial device authentication and configuration. In many pervasive computing and Internet-of-Things scenarios, it is often not possible to rely on the existence of a trusted third party or other network infrastructure for bootstrapping. Secure bootstrapping is the process by which a device gets the necessary configuration information and security credentials to become operational.
