Toward an energy efficient PKC-based key management system for wireless sensor networks
ISC Int. J. Inf. Secur., 2014
Due to wireless nature and hostile environment, providing of security is a critical and vital task in wireless sensor networks (WSNs). It is known that key management is an integral part of a secure network. Unfortunately, in most of the previous methods, security is compromised in favor of reducing energy consumption. Consequently, they lack perfect resilience and are not _t for applications with high security demands. In this paper, a novel method is proposed to improve the security of key management system based on broadcast messages from the base station. Another problem with WSNs is the cryptographic materials (such as private keys) stored in dead nodes. Adversaries may exploit these nodes to mount more effective attacks. Any secure key management system should also address this problem. It is argued that in the proposed method keying materials of dead nodes lose their validity, and therefore are of no use for an adversary. Finally, it is shown through simulation that the propo...
An Efficient and Secure Session Key Management Scheme in Wireless Sensor Network
Complexity, 2021
Wireless Sensor Network (WSN) is a particular network built from small sensor nodes. These sensor nodes have unique features. That is, it can sense and process data in WSN. WSN has tremendous applications in many fields. Despite the significance of WSN, this kind of network faced several issues. The biggest problems rising in WSN are energy consumption and security. Robust security development is needed to cope with WSN applications. For security purposes in WSN, cryptography techniques are very favorable. However, WSN has resource limitations, which is the main problem in applying any security scheme. Hence, if we are using the cryptography scheme in WSN, we must first guarantee that it must be energy-efficient. Thus, we proposed a secure hybrid session key management scheme for WSN. In this scheme, the major steps of public key cryptography are minimized, and much of the operations are based on symmetric key cryptography. This strategy extensively reduces the energy consumption of...
The wireless sensor networks needs security for transferring the sensed data to the base station. There are many possible ways to attack the transferred data, for reducing the attacks security is mostly needed for the network. Key management is the method of using cryptographic keys to provide security. The resources of wireless sensor networks must also be considered for the establishment of keys. This paper explains about the different mechanisms or protocols that are possible for wireless sensor networks to establish the authentication keys in resource-efficient manner. This paper also presents the different cryptographic methods that are used by the sensor networks for securing its data. This paper does not conclude any specific protocol which is suited for establishing cryptographic keys in resource-efficient manner. But the usage of protocols depends upon the applications of the wireless sensor networks.
An Energy-Efficient Security Node-Based Key Management Protocol for WSN
Applied Mechanics and Materials, 2013
A security node-based key management protocol is proposed for cluster-based sensor networks. Member nodes and cluster heads are responsible for data collection and transmission. Security nodes are responsible for key management. Security nodes restrain key management function of cluster heads, and reduce damage of captured cluster heads. Generation of security nodes and different kinds of keys is described. Performance analysis and simulation show that the proposed key management protocol consumes less energy, and its delay time of key generation is short. At the same time, the protocol can provide more collaborative authentication security for keys. It has strong resilience against node capture, and can support large scale network.
A unified security framework with three key management schemes for wireless sensor networks
Computer Communications, 2008
Pervasive computing environments find their practical manifestations through wireless sensor networks, which sense a relationship amongst themselves and the environment. Currently the proposed keying schemes for ensuring security, in wireless sensor networks, may be classified into public and private keying schemes, or their hybrid. However, an investigation in peer work underpins the fact that neither of these works relates the key management schemes with the granularity of key generation, distribution, renewal, and revocation. In this paper, we propose a unified security framework with three key management schemes, SACK, SACK-P, and SACK-H that incorporate symmetric key cryptography, asymmetric key cryptography and the hybrid, respectively. We have evaluated the key management schemes against a broad range of metrics such as energy, resource utilization, scalability and resilience to node compromises. Our evaluation comprises both analytical investigation and experimental validation. The results show that though SACK-P is heavy on resources, it provides maximal security and offers the best resilience to node compromises. On the contrary, SACK is very efficient in terms of storage and communication. Our results substantiate a relationship between the level of security and resource utilization and form a design benchmark for security frameworks.
Energy Efficient Key Management Scheme for Wireless Sensor Networks
2014
Designing an efficient key establishment scheme is of great importance to the data security in Wireless Sensor Networks. The traditional cryptographic techniques are impractical in Wireless Sensor Networks because of associated high energy and computational overheads. This algorithm supports the establishment of three types of keys for each sensor node, an individual key shared with the base station, a pair wise key shared with neighbor sensor node, and a group key that is shared by all the nodes in the network. The algorithm used for establishing and updating these keys are energy efficient and minimizes the involvement of the base station. Polynomial function is used in the study to calculate the keys during initialization, membership change and key compromise. Periodically the key will be updated. To overcome the problem of energy insufficiency and memory storage and to provide adequate security, the energy efficient scheme is proposed. It works well in undefined deployment environment. Unauthorized nodes should not be allowed to establish communication with network nodes. This scheme when compared with other existing schemes has a very low overhead in computation, communication and storage.
An Efficient and Secure Key Management Scheme for Hierarchical Wireless Sensor Networks
International Journal of Computer and Communication Engineering, 2012
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.
LIGHTWEIGHT KEY MANAGEMENT SCHEME FOR HIERARCHICAL WIRELESS SENSOR NETWORKS
Wireless Sensor Networks (WSNs) are critical component in many applications that used for data collection. Since sensors have limited resource, security issues have become a critical challenge in Wireless Sensor Networks. To achieve security of communicated data in the network and to extend the WSNs lifetime; this paper proposes a new scheme called Lightweight Key Management Scheme (LKMS). LKMS used Symmetric Key Cryptography that depends only on a Hash function and XOR operation. Symmetric Key Cryptography is less computation than Asymmetric Key Cryptography. Simulation results show that the proposed scheme provides security, save the energy of sensors with low computation overhead and storage.
Efficient and Secure Key Distribution Protocol for Wireless Sensor Networks
Sensors, 2018
Modern wireless sensor networks have adopted the IEEE 802.15.4 standard. This standard defines the first two layers, the physical and medium access control layers; determines the radio wave used for communication; and defines the 128-bit advanced encryption standard (AES-128) for encrypting and validating the transmitted data. However, the standard does not specify how to manage, store, or distribute the encryption keys. Many solutions have been proposed to address this problem, but the majority are impractical in resource-constrained devices such as wireless sensor nodes or cause degradation of other metrics. Therefore, we propose an efficient and secure key distribution protocol that is simple, practical, and feasible to implement on resource-constrained wireless sensor nodes. We conduct simulations and hardware implementations to analyze our work and compare it to existing solutions based on different metrics such as energy consumption, storage overhead, key connectivity, replay ...
