EAKRR : An energy-efficient key management in WSN with ECC-based cryptography

Environmental monitoring, industrial automation, and other applications require Wireless Sensor Networks (WSN). WSN must efficiently manage cryptographic keys for safe communication and energy efficiency. This study introduces “Energy-Aware Key Revocation and Rekeying” (EAKRR) to address energy efficiency and security in WSN using Elliptic Curve Cryptography (ECC). Energy-efficient key management is needed in WSN which have sensor nodes with limited resources and energy. EAKRR is designed to adapt to sensor node energy levels to make crucial key revocation and rekeying decisions while maintaining strong and resilient security. Energy profiling is used by EAKRR to assess sensor node energy consumption during cryptographic and operational operations. Energy conservation is achieved by localized key revocation when a node’s energy drops below a threshold. EAKRR also optimizes security and energy efficiency with ECC-based adaptive key length modifications. EAKRR is compared to LEACH and AES to determine its efficacy. The results show that EAKRR is highly energy efficient, extending the network’s lifespan and maintaining security. Cryptographic operations are careful and wise because they can adjust to energy levels in real time. The balance between security and energy usage shows that ECC-based encryption works. Energy-efficient key management in WSN is crucial. EAKRR solves WSN problems by saving energy, extending network life, and securing the network.

Enhancing Security in Wireless Sensor Networks With Key Management Techniques

In several fields, including environmental monitoring and healthcare, wireless sensor networks (WSNs) have emerged as a vital technology. Security is a critical concern for WSNs, as these networks are often deployed in hostile environments where attackers may attemptto compromise the integrity and confidentiality of data. Key management is a key component of WSN security because it is employed to create and maintain secure channels for communication between nodes. This paper provides an overview of key management techniques for WSNs, including symmetric and asymmetric key distribution, hash-based key distribution, and threshold cryptography. We also discuss the strengths and weaknesses of each technique, as well as their suitability for different types of WSN applications. Finally, we identify key research challenges in the field of WSNs' key management, including the development of lightweight and energy-efficient key management protocols and the integration of key management with other security mechanisms such as intrusion detection and secure routing.

Energy aware and fast authentication scheme using identity based encryption in wireless sensor networks

Wireless sensor networks described as an emerging new technology with a very promising future. Advances made in wireless sensor networks (WSNs) are the merging of advanced electronic and wireless technologies. Due to the popularity gained by the wireless environment, Security is the main concern. Node authentication without compromising lifespan of the networks is practically a daunting task. This research work introduces a new model, IBE-ECC that administers the energy of sensor nodes with faster authentication process. Signature verification model is deployed to achieve faster authentication process. Nevertheless, the public key-based strategies eliminate the security process but their verification process takes larger time. Therefore, authentication speed is a major constraint of our research endeavor. The proposed scheme is design to achieve high security and fast authentication with energy efficiency. It uses identity-based encryption on elliptic curve cryptography and a user authentication with an energy efficient key management. Further, to improve the speed of the authentication, it reduces the signature size so that it would accelerate signature verification faster. Hence, the proposed scheme will provide a secure key management, energy efficiency, fast authentication and additionally, computation overhead and communication costs are minimized. Finally, the experimental result demonstrates that the proposed strategy obtains 4797 ms higher execution efficiency and 45. 53% lower computation costs than existing schemes.

An Energy-Efficient Key Management Scheme using Trust Model for Wireless Sensor Network

<p>In wireless sensor networks (WSNs), secret shared keys must be established with the neighboring nodes in order to achieve secure communication. The challenge issues for secured communication in WSN are the Key management. Location Dependent Key (LDK) management is a suitable scheme when compared to other location based key management schemes because of lesser memory space requirement and lesser number of keys to be stored on each sensor node. However, the LDK is affected by communication interference problem which is solved by the key is distributed based on trust model. The distributed key updates and revocation processes are effectively resist inside attackers. An energy-efficient Key Management with Trust Model (KM-TM) for WSNs is proposed to achieve the secured communication and the nodes are resisting from the attackers. The performances of proposed KM-TM for WSNs are evaluated in terms of trustworthiness of sensor nodes and security breaches more effectively. </p>

Energy-efficient Cluster-based Mechanism for WBAN Communications for Healthcare Applications

Wireless body area networks (WBANs) are formed with the help of tiny health monitoring sensors on the human body in order to collect and communicate the human personal data. WBANs provides a solution to facilitate the tasks performed in the medical sector, and minimize the chances of errors during the process of medical diagnosis. However, using an expensive key management method is not feasible in highly resource-constrained WBANs. Therefore, we propose and evaluate an energy-efficient key management scheme for WBANs that takes into account available resources of a node during the whole life cycle of key management. Our proposed scheme is a cluster-based hybrid security energy efficient framework. By using multiple clusters, energy-efficiency can be ensured. The performance comparison of our proposed cluster-based key management scheme and low-energy adaptive clustering hierarchy (LEACH)-based key agreement scheme and energy – efficient mechanism shows that the proposed scheme is more energy-efficient, and provides better network lifetime.

Energy-efficient cluster-based security mechanism for intra-WBAN and inter-WBAN communications for healthcare applications

Wireless body area networks (WBANs) are formed by using tiny health monitoring sensors on the human body in order to collect and communicate the human personal data. WBANs serve as a solution to facilitate the tasks performed in the medical sector, and minimize the chances of errors during the process of medical diagnosis. Due to the unreliable wireless media, the communication in a WBAN is exposed to a variety of attacks. These attacks pose major threats to WBAN security. In order to overcome these threats, several cryptographic techniques have been proposed in the recent past. Effectiveness of these cryptographic techniques largely depends on a good key management scheme. However, using an expensive key management scheme is not feasible in highly resource-constrained WBANs. Therefore, we propose and evaluate an energy-efficient key management scheme for WBANs that takes into account available resources of a node during the whole life cycle of key management. Our proposed scheme is a cluster-based hybrid security framework that supports both intra-WBAN and inter-WBAN communications. By using multiple clusters, energy-efficiency can be ensured. The cluster formation process itself is secured by using electrocardiogram (EKG)-based key agreement scheme. The proposed technique is hybrid because we use both preloading of keys and physiological value-based generated keys. We use highly dynamic and random EKG values of the human body for pairwise key generation and refreshment. The performance comparison of our proposed cluster-based key management scheme and low-energy adaptive clustering hierarchy (LEACH)-based key agreement scheme shows that the proposed scheme is secure, more energy-efficient, and provides better network lifetime.

An Efficient and Secure Key Management Scheme for Hierarchical Wireless Sensor Networks

 Abstract—Key management in wireless sensor network is a complex task due to its nature of environment. Wireless sensor network comprise of large number of sensor nodes with different hardware abilities and functions. Due to the limited memory resources and energy constraints, complex security algorithms cannot be used in sensor networks. Therefore, an energy efficient key management scheme is necessary to mitigate the security risks. In this paper, we present an Efficient and Secure Key Management Scheme for Hierarchical Wireless Sensor Network (ESKMS). The proposed technique distributes the keys within a cluster efficiently and updates the pre-deployed keys to mitigate the node compromise attack. We also provide a detailed security analysis of our ESKMS protocol and show its advantages in avoiding different type of attacks from malicious nodes. Finally, using NS-2 simulator, the results shows that ESKMS is more energy efficient and provides a longer network lifetime compared to the existing key management schemes.

Group key management scheme for large-scale sensor networks

Wireless sensor networks are inherently collaborative environments in which sensor nodes self-organize and operate in groups that typically are dynamic and mission-driven. Secure communications in wireless sensor networks under this collaborative model calls for efficient group key management. However, providing key management services in wireless sensor networks is complicated by their ad-hoc nature, intermittent connectivity, large scale, and resource limitations. To address these issues, this paper proposes a new energy-efficient key management scheme for networks consisting of a large number of commodity sensor nodes that are randomly deployed. All sensor nodes in the network are anonymous and are preloaded with identical state information. The proposed scheme leverages a location-based virtual network infrastructure and is built upon a combinatorial formulation of the group key management problem. Secure and efficient group key initialization is achieved in the proposed scheme by nodes autonomously computing, without any communications, their respective initial group keys. The key server, in turn, uses a simple location-based hash function to autonomously deduce the mapping of the nodes to their group keys. The scheme enables dynamic setup and management of arbitrary secure group structures with dynamic group membership.
