The rapid development of Internet of things (IoT) technology has made the IoT applicable in many areas of life and has contributed to the IoT’s improvement. IoT devices are equipped with various sensors that enable them to perform the tasks they were designed for. The use of such devices is associated with securing communication between devices and users. The key stages of communication are the processes of authentication and the process of agreeing on session keys because they are the basis of the subsequent communication phases. The specially designed security protocols are used to secure communication. These protocols define the course of communication and cryptographic techniques employed for securing. In this article, we have reviewed the latest communication protocols designed to secure authentication processes and agree on session keys in IoT environments.

The Internet of Things (IoT) represents a dynamic infrastructure, leveraging sensing and network communication technology to establish ubiquitous connectivity among people, machines, and objects. Due to its end devices’ limited computing resources and storage space, it is not feasible to merely transpose traditional internet security technologies directly to IoT endpoints. Maintaining security while concurrently ensuring performance is a particularly challenging endeavor. This paper provides a review of key agreements and authentication protocols pivotal to the security of IoT. First, this survey discusses the applications that need authentication and key agreement to strengthen their security and current research on these application fields. Subsequently, this paper engages in an in-depth exploration of the phase involved in the scheme of authentication and key agreement, including an examination of the cryptographic techniques employed within these processes. This survey also thoroughly studies the scheme’s security services, potential attacks, formal analysis and informal analysis to ensure resilience against such threats. This study aims to provide a profound understanding of the recent research on authentication and key agreement in IoT applications. It strives to contribute towards strengthening security systems for IoT applications, ensuring their sustainability in the face of evolving threats.
In the Internet of Things (IoT) environment, more types of devices than ever before are connected to the internet to provide IoT services. Smart devices are becoming more intelligent and improving performance, but there are devices with little computing power and low storage capacity. Devices with limited resources will have difficulty applying existing public key cryptography systems to provide security. Therefore, communication protocols for various kinds of participating devices should be applicable in the IoT environment, and these protocols should be lightened for resources-restricted devices. Security is an essential element in the IoT environment, so for secure communication, it is necessary to perform authentication between the communication objects and to generate the session key. In this paper, we propose two kinds of lightweight authentication and key agreement schemes to enable fast and secure authentication among the objects participating in the IoT environment. The first scheme is an authentication and key agreement scheme with limited resource devices that can use the elliptic curve Qu-Vanstone (ECQV) implicit certificate to quickly agree on the session key. The second scheme is also an authentication and key agreement scheme that can be used more securely, but slower than first scheme using certificateless public key cryptography (CL-PKC). In addition, we compare and analyze existing schemes and propose new schemes to improve security requirements that were not satisfactory.
The advent of Internet of Things (IoT) ushers in a significant potential to integrate individuals, devices, and data, leading to a profound change in our professional and social environments. The small, resource-constrained IoT devices are usually deployed to collect various types of critical data in remote or unmonitored locations. Due to extensive interconnectivity, limited resources, and inadequate security design, IoT systems are vulnerable to communication-specific cyber threats, which aim to disrupt operations, steal sensitive information, or cause damage. To resolve the security concerns in IoT communications, many recent efforts have been devoted to designing authenticated key agreement protocols for IoT systems. However, not only most of the existing solutions fail to adopt cost-effective techniques for resource-limited IoT devices, but also they ignore the differentiation among various data types in the established session keys. A few approaches use traditional physical unclonable functions (PUFs) to address resource concerns, yet they introduce new security issues into IoT systems. Once the PUF cryptographic information is compromised by machine learning attacks, the entire authentication framework collapses. Therefore, in this paper we propose an authenticated key agreement protocol for device-to-gateway communication in IoT systems based on Chebyshev polynomial and probability-based PUF. We examine the proposed protocol’s security features through formal security validation. We also conduct performance evaluation through a simulation-oriented study, and the results clearly prove that the proposed protocol offers superior security and privacy, while maintaining low computational overhead.
The Internet of Things (IoT) has become an important technology which permits different devices and machines to interconnect with each other using heterogeneous networks. The integration of numerous techniques is expected to offer extraordinary growth in future and current promising applications of IoT. In these days, the secure communication among interconnected IoT components has become an important issue of concern. Therefore, it has become a foremost need to design such authentication protocol which can make the secure communication among IoT components. In this article, we proposed an identity-based authentication and key agreement protocol for the IoT environment in order to offer the secure communication between various IoT entities. The devised protocol utilizes the physically unclonable function which helps to robustly resist the physical attack on IoT components. We analyze the proposed protocol informally which clearly shows that the proposed protocol offers the perfect forward secrecy, device anonymity and untraceability and also resists the desynchronization, IoT node impersonation and server impersonation attacks. The security features of proposed protocol are also analyzed formally using well known Random Oracle Model (ROM). Moreover, the performance of the devised protocol has also been determined in terms of communication and computational overhead. The performance and security analysis shows the supremacy of the devised protocol over the various related protocols.
The Industrial Internet of Things (IIoT) is the application of the Internet of Things (IoT) in the industrial field. IIoT allows users to remotely access industrial equipment and the data in it, which also brings certain challenges to the security of industrial data. Authentication and key agreement protocols are very effective security technologies in the matter of protecting industrial data. There is a large amount of research work on authentication protocols in IIoT, but most of the protocols have security weaknesses. Recently, Rafique et al. proposed a multi-factor protocol in IIoT that can accomplish authentication and session key establishment through a gateway. Rafique et al. claimed that their protocol is secure, unfortunately, we carefully analyze the protocol of Rafique et al. and find some security flaws, i.e., it is vulnerable to insider attack and known session-specific temporary information (KSSTI) attack, and unable to provide forward security. We explore the factors of insecurity and propose an enhanced multi-factor secure authentication and key agreement protocol in IIoT. The new protocol improves the security of the protocol while using only symmetric cryptography, hash function, and XOR operation. Formal security analysis and informal security discussions demonstrate that the new protocol is resistant to a variety of known attacks. After performance analysis, our protocol has lower computational cost, and increases no significant communication cost, while providing more secure and robust properties.
The Internet of Things (IoT) is among the most promising technologies of the future, and its development has garnered attention worldwide. However, the rise of the IoT has been accompanied by a proportionate increase in security concerns regarding communication between IoT entities. Recently, Alzahrani et al. proposed an identity-based authentication and key agreement protocol for an IoT environment, wherein a physically unclonable function was employed. They claimed that their protocol can resist various types of attacks; however, after thorough analysis, we determined it to be ineffective against privileged internal attacks, physical IoT device capture attacks, stolen-verifier attacks, and known temporary information exposure attacks. To resolve these security weaknesses, we propose a new authentication and key agreement protocol. In addition, we demonstrate that the proposed protocol is provably secure in real-or-random (ROR) model and Burrows–Abadi–Needham (BAN) logic, resisting known attacks while incurring low communication and computation costs.
