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

Low-Energy Symmetric Key Distribution in Wireless Sensor Networks [PDF]
In this work, a scheme for key distribution and network access in a Wireless Sensor Network (WSN) that utilizes Identity-Based Cryptography (IBC) is presented. The scheme is analyzed on the ARM920T processor and measurements were taken for the runtime and energy of its components.

Domain-based key management for heterogeneous wireless sensor networks
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

Grouping Sensors for the Key Distribution of Implicit Certificates in Wireless Sensor Networks
As sensor nodes communicate via wireless channels, information security is essential for wireless sensor networks. Efficient protection mechanisms to ensure data security among nodes are critical. This study developed the bi-directed grouping (top-down grouping (TDG) and bottom-up grouping (BUG)) methods.

A near infrared‐responsive microscale cantilever is developed using a 3D‐printable composite based on photocurable resin consisting of sepiolite and graphene flakes. The material absorbs 1064 nm light, causing shape transformation with an average displacement of 1.3 mm in 1.7 s. Displacement is measured via video recording.
