Internet of Things brings convenience to the social life, at the same time, putting forward higher requirements for the security of data transmission and storage. Security incidents based on industrial Internet of Things have occurred frequently recently, which should be given full consideration. The identity-based authenticated key agreement protocol can solve these security threats to a certain extent. Recently, a lightweight identity-based authenticated key agreement protocol for Industrial Internet of Things, called ID-2PAKA protocol, was claimed to achieve secure authentication and meet security properties. In this paper, we show that the ID-2PAKA protocol is insecure in identity authentication and cannot resisting ephemeral key compromise impersonation attack.

With the significant development of the Internet, Internet of Things (IoT) has become an emerging technology in many industries. To support security and privacy in the Industrial IoT environment, a user may interact with another user on the Internet to share confidential information, which requires an authenticated communication channel. To meet this demand, in this article the authors developed an identity-based two-party authenticated key agreement (ID-2PAKA) protocol that allows two users to communicate securely and share sensitive data across IoT-enabled regions. Similar protocols found in the literature either proven to be insecure or carry the burden of high communication and computational costs. The proposed ID-2PAKA protocol is analyzed in the random oracle model to achieve provable security based on the hardness assumptions of computational Diffie-Hellman and bilinear Diffie-Hellman problems. The performance analysis of the proposed ID-2PAKA protocol is performed using the pairing-based cryptography library. The comparative results from the perspective of the computation and communication costs against the competing protocols showed that the proposed ID-2PAKA protocol is secure and efficient.
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 Industrial Internet of Things (IIoT) refers to the expansion and application of the Internet of Things (IoT) in various industrial settings. Despite the numerous applications of the Industrial Internet of Things and its numerous advantages, the security of data exchanged in the Industrial Internet of Things remains one of the challenges facing this emerging technology. When this data is accessed and manipulated by attackers, the consequences may include disruptions to production processes, financial losses, and even threats to human life. Therefore, given the demand not only to protect information but also to ensure the health and safety of industries, the utmost attention should be paid to the security of data and entities involved in the Industrial Internet of Things. In this paper, an innovative protocol for authentication and key agreement between Industrial Internet of Things devices and cloud servers is proposed. This protocol is designed to deal with security threats and meet various security requirements. The Scyther tool has been used to evaluate the performance and security of the proposed scheme. The evaluation results demonstrate that the proposed protocol effectively maintains all security aspects and outperforms similar schemes in terms of efficiency.
The Internet of Things (IoT) is an emerging technology that has become popular in many applications, such as transportation, agriculture, healthcare, industrial automation, robotics, etc. IoT devices are interconnected via the Internet, and secure message communication between them is a challenging task. An authenticated key agreement (AKA) protocol can solve such an issue. This article designed and implemented an identity-based three-party AKA (IoT-ID3PAKA) protocol to establish a shared session key among three IoT devices. The current state-of-the-art identity-based 3PAKA (ID-3PAKA) protocols are unsuitable for resource-constrained IoT devices because almost all of them undergo various security attacks and require higher execution and communication overheads. The provable security of the proposed IoT-ID3PAKA protocol relies on the hardness assumption of the elliptic curve-based computational Diffie–Hellman problem. The execution time of IoT-ID3PAKA for the security levels: 80, 112, 128, 192, and 256 bits on a Raspberry Pi 4 device is estimated and compared with the existing ID-3PAKA protocols.
Industrial Internet-of-Things (IIoT) is the basis of Industry 4.0, which extends Internet connectivity beyond traditional computing devices like computers and smartphones to the physical world for improving efficiency and accuracy while reducing the production cost. However, there are tremendous security threats to IIoT, such as IIoT device hijacking and data leaks. Therefore, a lightweight authenticated key agreement (AKA) protocol is commonly applied to establish a session key for securing the communication between IIoT devices. To protect the previous session keys from being compromised, perfect forward secrecy (PFS) has been one of the most important security properties of AKA. In this article, we present an efficient PFS-enabled AKA protocol for IIoT systems, which is developed based on a new dynamic authentication credential (DAC) framework, without using any public-key cryptographic primitives. It is worth noting that our protocol is also faster than the state-of-the-art DAC-based AKA protocols with PFS. Moreover, we give the formal security result of the proposed protocol in the random oracle model.
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.
