Shortening the security parameters in lightweight WSN applications for IoT - lessons learned
Anna Sojka-Piotrowska, Peter Langendöerfer · 2017
The Wireless Sensor Networks (WSN) are important part of Internet of Things. And one of the important requirements of WSN is to ensure that the data exchanged within these networks is secured. Since WSNs consist of resource constrained devices, it is crucial to investigate new, lightweight security solutions, which ensure fast computations, reduced energy consumption and desired level of security. This paper proposes using cryptographic algorithms based on Elliptic Curves, but with reduced key lengths, what makes them suitable for WSN. For this new idea, the security analysis was performed and the application areas were proposed.
