A knowledge based system approach in securing distributed wireless sensor networks
This addresses security vulnerabilities in distributed wireless sensor networks, which are critical for real-world applications, but the approach appears incremental as it combines existing techniques like AES and expert systems.
The paper tackles securing information transmission in wireless sensor networks by proposing a combined hardware-software architecture with authentication, AES encryption, and an expert system for attack detection, resulting in a method to reduce sensor trust coefficients upon detecting anomalies.
Sensor networks technologies had proved their great practicability in the real world, being just a matter of time until this kind of networks will be standardized and used in the field. This paper presents a new approach to secure the transmission of information in sensor networks and is based on a combined hardware-software architecture using three components: a) a mechanism to provide sensor authentication and secret key distribution; b) AES symmetrical encryption algorithm with predistributed keys; and c) an attack detection stratagem using an expert system based on the prediction of the values provided by the sensors, followed by reducing the sensor trust coefficient.
