“…For group authentication and key management, researchers have put forth a number of methods, including effective Group Key Establishment (GKE) and GKM schemes. Schemes for GKE have been designed for resourceconstrained network architectures by applying ECC in [25], [26]. The authors of [8] and [9] discuss several key graph types that are utilised for the user-device structure and how they affect communication and processing costs.…”

The Internet of Things (IoT) extends Internet connectivity to resource-constrained devices such as sensors and actuators. It is prone to several security threats and attacks, due to which defence mechanisms such as encryption, message authentication codes, authentication, etc., need to be employed. Several IoT scenarios require secure communication to and data acquisition from multiple devices, which constitute a ''group''. Also, in dynamic IoT scenarios, devices join or leave a group from time to time, due to which the group keys, which are used for multicasting information within the group, need to be efficiently updated. We propose a novel scheme, based on factorial trees and the Chinese Remainder Theorem, for efficient Group Key Management. Our proposed scheme prevents malicious users from accessing information from a group and efficiently updates the group keys when devices join or leave a group, while guaranteeing forward and backward secrecy. We evaluate the performance of the proposed scheme via extensive mathematical analysis and numerical computations, and show that it outperforms schemes proposed in prior work in terms of the communication and computation costs incurred by IoT devices.

“…Other than key tree based methods, there exist a variety of non-interactive key agreement protocols [12][13][14][15][16] which are applicable to WSNs or IoT networks. A secure group key establishment based on Elliptic Curve Cryptographic (ECC) operations was proposed in [12] for IoT networks. In this work, the authors have used one-way cryptographic accumulators to enable the connection between the gateway and IoT nodes to establish secure group keys and use them for further communications.…”

Due to limitations of IoT networks including limited bandwidth, memory, battery, etc., secure multicast group communication has gained more attention, and to enable that a group key establishment scheme is required to share the secret key among the group members. The current group key establishment protocols were mostly designed for Wireless Sensor Network, and they require device interaction, high computation costs, or high storage on the device side. To address these drawbacks, in this paper we design LMGROUP, a lightweight and multicast group key establishment protocol for IoT networks, that is based on Elliptic Curve Integrated Encryption Scheme and HMAC verification and does not require device interaction. We also suggest an algorithm for unpredictable group member selection. Our experimental result of implementing LMGROUP indicates it has low storage, low computation, and low communication costs. Furthermore, the formal security verification indicates LMGROUP is secure and robust against different attacks.

“…In [3], the authors propose an efficient and lightweight 3-factor authentication and key establishment scheme, based on Biohashing and the Rabin Cryptosystem, for WSNs to securely connect to the Internet. Elliptic Curve Cryptography has also found novel applications in designing keying protocols for constrained network architectures [18]- [21]. Online validation of public key certificates is another problem in the field of IoT security.…”

Many Internet of Things (IoT) scenarios require communication to and data acquisition from multiple devices with similar functionalities. For such scenarios, group communication in the form of multicasting and broadcasting has proven to be effective. Group Key Management (GKM) involves the handling, revocation, updation and distribution of cryptographic keys to members of various groups. Classical GKM schemes perform inefficiently in dynamic IoT environments, which are those wherein nodes frequently leave or join a network or migrate from one group to another over time. Recently, the 'GroupIt' scheme has been proposed for GKM in dynamic IoT environments. However, this scheme has several limitations such as vulnerability to collusion attacks, the use of computationally expensive asymmetric encryption and threats to the backward secrecy of the system. In this paper, we present a highly efficient and secure GKM protocol for dynamic IoT settings, which maintains forward and backward secrecy at all times. Our proposed protocol uses only symmetric encryption, and is completely resistant to collusion attacks. Also, our protocol is highly flexible and can handle several new scenarios in which device or user dynamics may take place, e.g., allowing a device group to join or leave the network or creation or dissolution of a user group, which are not handled by schemes proposed in prior literature. We evaluate the performance of the proposed protocol via extensive mathematical analysis and numerical computations, and show that it outperforms the GroupIt scheme in terms of the communication and computation costs incurred by users and devices.
