Implementation of Elliptic Curves in the Polynomial Blom Key Pre-Distribution Scheme for Wireless Sensor Networks and Distributed Ledger Technology

Journal of Sensor and Actuator Networks, 2023
One of the challenges in securing wireless sensor networks (WSNs) is the key distribution; that is, a single shared key must first be known to a pair of communicating nodes before they can proceed with the secure encryption and decryption of the data. In

Random key pre-distribution with transitory master key for wireless sensor networks [PDF]

Proceedings of the 5th international student workshop on Emerging networking experiments and technologies, 2009
Many Wireless Sensor Networks (WSNs) employ security schemes based on the symmetric encryption, which requires the establishment and management of cryptographic keys. This paper presents a new key management scheme based on Random Key Pre-Distribution. The novelty of the proposed approach is the introduction of a keyed transformation with a Transitory ...

Rapid Diagnostics of Reconfigurable Intelligent Surfaces Using Space‐Time‐Coding Modulation

Advanced Functional Materials, EarlyView.
A fast reconfigurable‐intelligent‐surface (RIS) diagnostics method is proposed based on spatio‐temporal modulation with orthogonal codes. Theoretical analysis demonstrates a clear distinction in code channel power between normal and faulty elements. Simulations validate its feasibility under high fault ratios and varying receiving angles.
