Distributed Key Management to Secure IoT Wireless Sensor Networks in Smart-Agro

Abstract

With the deepening of the research and development in the field of embedded devices, the paradigm of the Internet of things (IoT) is gaining momentum. Its technology's widespread applications increasing the number of connected devices constantly. IoT is built on sensor networks, which are enabling a new variety of solutions for applications in several fields (health, industry, defense, agrifood and agro sectors, etc.). Wireless communications are indispensable for taking full advantage of sensor networks but implies new requirements in the security and privacy of communications. Security in wireless sensor networks (WSNs) is a major challenge for extending IoT applications, in particular those related to the smart-agro. Moreover, limitations on processing capabilities of sensor nodes, and power consumption have made the encryption techniques devised for conventional networks not feasible. In such scenario, symmetric-key ciphers are preferred for key management in WSN; key distribution is therefore an issue. In this work, we provide a concrete implementation of a novel scalable group distributed key management method and a protocol for securing communications in IoT systems used in the smart agro sector, based on elliptic curve cryptography, to ensure that information exchange between layers of the IoT framework is not affected by sensor faults or intentional attacks. In this sense, each sensor node executes an initial key agreement, which is done through every member's public information in just two rounds and uses some authenticating information that avoids external intrusions. Further rekeying operations require just a single message and provide backward and forward security.

Towards Green Computing Oriented Security: A Lightweight Postquantum Signature for IoE

“…The group key support strategy is also incorporated for reducing the communication overhead in key distribution. Similarly, to deal with malfunctioning of the IoT enabled systems, Hussein et al [35] investigated a secure protocol to maintain the secrecy rate in IoT environments and to reduce the energy consumption at IoT nodes. However, both these ECC frameworks are vulnerable against quantum attacks as edge centric faster and efficient security enabler nodes have not been considered to support the security operations of resources constrained IoT nodes.…”

Blockchain-based privacy and security model for transactional data in large private networks

“…Nodes connected to the Internet of Things (IoT) may gather user data from their environs, distribute that data among themselves, and communicate with other embedded software systems in their networks 1 . They create a substantial amount of user data, and nodes may not always be able to rely on one another during crucial communications.…”

Security Management Suitable for Lifecycle of Personal Information in Multi-User IoT Environment

“…Authentication between IoT devices and users has already been dealt with in many studies and is therefore not included in this paper [10,20,21,33]. We assume that the user has registered an identifier and a secret code to the IoT device through a secure channel during the authentication process.…”
