Exploring State-of-the-Art Cryptography: A Systematic Exploration of Advanced Approaches for IoT Device Authentication

Security of IoT devices has become a major issue since it started expanding. Authentication is the key component for the security of IOT devices. But using the traditional cryptographic security methods can be a way more expensive in terms of storage, processing speed, and capacity and they cannot be used with Internet of Things hardware where the resources are poor. Autonomous communication between devices opens a range of application possibilities; however, it is restricted by the resource scarcity of the machines and devices in the networks. The use of advanced cryptographic techniques has facilitated secure and effective device authentication for IoT devices. This study provides an overview of numerous cryptographic techniques for IoT device authentication. Different research papers were explored in areas related to security and authentication on the Internet of Things (IoT) domain. In these papers, researchers present novel authentication and security techniques that aim at addressing the unique challenges presented by IoT devices such as constraint of resources and constrained computing power. These papers also propose various methods to enhance the device security and authentication which includes the use of encryption algorithms, digital signatures, secure communication protocols, and biometric authentication. The proposed solutions of this paper offer improved security and efficiency in comparison to other existing authentication methods. Inclusive of all, these papers contribute valuable insights into the field of IoT device authentication and provide assuring solutions to the security challenges posed by IoT devices.
