The Best Authentication protocol for IoT Networks Using Biometrics

In recent years, the IT business has exploded, mostly due to the development of new Internet-based technologies. In this sense, the Internet has successfully adopted technologies such as wireless access, high-speed connectivity, APIs, and electronic services. Developers and IT professionals have also created connectivity systems such as Wi-Fi, Bluetooth, and RFID. Simultaneously, the technological expenses of Internet connectivity for all smaller devices, such as laptops and smartphones, tend to fall year after year.


Biometrics in IOT

New technologies, such as artificial intelligence, big data, cloud computing, mobile sensor networks, and the Internet of Things, have emerged, allowing people to share in far more ways. This new technology transforms the world, opens up new commercial options, provides new solutions to improve safety, convenience, and efficiency, reduces human labour, and allows for new data collecting and analysis methods. To meet the safety needs of both of these new technologies, it is critical to focus on encryption as the first line of security against potential aggressors.


In recent years, cryptosystems have been expected to solve security through authentication procedures. Hash functions, symmetric/asymmetric algorithms, digital signatures, and ID-based cryptography are some of the most important cryptographic techniques.

The most crucial thing for IoT services is to provide mobile user authentication with flexible biometric authentication and a core entry management architecture.


Protocol -

The suggested multi-factor biometric authentication process consists of the following stages:

• Registration of users

• Authentication of users


Phase of User Registration: The client (Ci) who wishes to utilise his or her smart device to access the IoT platform must register with the Gateway Base Station during this process (GN). The linked sensor nodes will be able to acquire access to the IoT system on demand once the client has infiltrated the gateway network.


The consumer completes the encryption stage to obtain a mutual session key, which is utilised to establish a secure connection. After successful activation, the user can authenticate the IoT network and network nodes.

Phase of User Authentication: To get access to the IoT service by any node, the client makes a verification request to the designated node (Nj) within the IoT network, rather than the Gateway Device (GN). Client Ci will connect to any needed node within the IoT platform via the authentication point once registration is complete. To begin the authentication process, the user must first log into the appropriate IoT service implementation on his or her smartphone, such as health surveillance, smart home tracking, and so on.

Users can register and authenticate using biometrics and passwords in the proposed system.

Evaluation of Security


Standard authentication is provided, passwords are preserved, and specific vulnerability designs are avoided in the proposed system. IoT nodes are resource-constrained, all-purpose computers. To ensure that operational costs are minimal, the new authentication system's quality must be tested. This can be done using a variety of factors, such as communication, storage, and further cost estimates.


Assume that the customer's smartphone has gone missing or has been stolen. Through the control assault, extract sensitive info from the stolen device's history. The intruder is thought to be familiar with the HPi, GIi, xi, and yi structures. CIDi, the user ID, is not explicitly stored in memory; it is stored in a dressed form. Furthermore, the password and biometric information are blended with concealed random data; otherwise, the intruder would be unable to obtain such values. As a result, the suggested system is immune to attacks from smartphones. Intruders in the encryption process can be seen looking at the transmitted messages HPi, GIi, xi, yi, TS1 and HPi, GIi, xi, yi, TS1.


The framework described solely uses XOR operations for secure and lightweight computation, and it provides enhanced IoT performance in asset-limited systems.

This protocol makes use of the Gateway Node layout, which the user must first access through the Gateway Node. Customers are connected to the sensor node needed to cease operation by their smart technology once they have authenticated. Because it employs perceptual Hash and computer-intensive XOR operations, the protocol is compact, making it appropriate for IoT systems with limited resources.
