Monitoring Cryptographic Strength of Wireless Sensor Networks using ZKP
Arunakumari Bellamkonda, Kodipaka Rajeshwar Rao, Siddharth Nagar · 2012
The security mechanisms used for wired networks cannot be directly used in sensor networks as there is no user-controlling of each individual node, wireless environment, and more importantly, scarce energy resources. In this paper, we address some of the special security threats and attacks in Wireless Sensor Networks offer a powerful methodology to monitor environments, and have a lot of interesting applications, We propose a scheme for detection of distributed sensor cloning attack and use of zero knowledge protocol for verifying the authenticity of the sender sensor nodes. The cloning attack is addressed by attaching a unique fingerprint to each node that depends on the set of neighboring nodes and itself. The fingerprint is attached with every message a sensor node sends. The Zero knowledge protocol is used to ensure non transmission of crucial cryptographic information in the wireless network in order to avoid man-in-the middle attack and replay attack. The paper presents a detailed analysis for various scenarios and also analyzes the performance and cryptographic strength.
