Hybrid Key pre-distribution scheme for wireless sensor network based on combinatorial design [PDF]

Journal of Advances in Computer Engineering and Technology, 2015
Key distribution is an important problem in wireless sensor networks where sensor nodesare randomly scattered in adversarial environments.Due to the random deployment of sensors, a list of keys must be pre-distributed to each sensor node before ...

Mutual trust method for forwarding information in wireless sensor networks using random secret pre-distribution

Advances in Mechanical Engineering, 2016
In wireless sensor networks, sensing information must be transmitted from sensor nodes to the base station by multiple hopping. Every sensor node is a sender and a relay node that forwards the sensing information that is sent by other nodes.

A Hybrid Key Management Scheme for WSNs Based on PPBR and a Tree-Based Path Key Establishment Method

Sensors, 2016
With the development of wireless sensor networks (WSNs), in most application scenarios traditional WSNs with static sink nodes will be gradually replaced by Mobile Sinks (MSs), and the corresponding application requires a secure communication environment.

Domain-based key management for heterogeneous wireless sensor networks

Tongxin xuebao, 2009
Key management was one of the most challenging security problems in wireless sensor networks. Based on the random key pre-distribution scheme, a new scheme was proposed for heterogeneous wireless sensor networks using deployment knowledge of the node and

Implementing RSA for Wireless Sensor Nodes

Sensors, 2019
As wireless sensor networks (WSNs) become more widespread, potential attacks against them also increase and applying cryptography becomes inevitable to make secure WSN nodes. WSN nodes typically contain only a constrained microcontroller, such as MSP430,

Using combined keying materials for key distribution in wireless sensor networks

21st Annual IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, 2010
In this paper, we propose a probabilistic key predistribution scheme for wireless sensor networks that increases connectivity of the basic scheme while keeping sizes of keyring and key pool fixed. We introduce the concept of XORed key, which is the bitwise XOR of two regular (a.k.a. single) keys.
