A Survey on Key Agreement and Authentication Protocol for Internet of Things Application

Mohammad Kamrul Hasan, Zhou Weichen, Nurhizam Safie +2 more

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.

Security Evaluation of Provably Secure ECC-Based Anonymous Authentication and Key Agreement Scheme for IoT

Kisung Park, Myeonghyun Kim, Youngho Park

The proliferation of the Internet of Things (IoT) has worsened the challenge of maintaining data and user privacy. IoT end devices, often deployed in unsupervised environments and connected to open networks, are susceptible to physical tampering and various other security attacks. Thus, robust, efficient authentication and key agreement (AKA) protocols are essential to protect data privacy during exchanges between end devices and servers. The previous work in "Provably Secure ECC-Based Anonymous Authentication and Key Agreement for IoT" proposed a novel AKA scheme for secure IoT environments. They claimed their protocol offers comprehensive security features, guarding against numerous potential flaws while achieving session key security. However, this paper demonstrates through logical and mathematical analyses that the previous work is vulnerable to various attacks. We conducted a security analysis using the extended Canetti and Krawczyk (eCK) model, which is widely employed in security evaluations. This model considers scenarios where an attacker has complete control over the network, including the ability to intercept, modify, and delete messages, while also accounting for the potential exposure of ephemeral private keys. Furthermore, we show that their scheme fails to meet critical security requirements and relies on flawed security assumptions. We prove our findings using the automated validation of internet security protocols and applications, a widely recognized formal verification tool. To strengthen attack resilience, we propose several recommendations for the advancement of more robust and efficient AKA protocols specifically designed for IoT environments.
