Ensuring Data Integrity and Transmission Security in WSN through Zero Watermarking and Diffie-Hellman Techniques.

Problem Definition

This problem definition highlights the pressing issue of data security in Wireless Sensor Networks (WSNs), where sensor nodes are deployed in unreliable and potentially hostile environments. The current approaches to enhancing security, such as digital watermarking and steganography, are not foolproof as they are susceptible to various attacks like watermark modification, packet forgery, and packet drop attacks. Furthermore, the inherent vulnerability of sensor nodes in these environments exposes them to additional threats like packet replay, modification, forgery, and drop attacks. As a result, ensuring data confidentiality, integrity, freshness, and reliability becomes crucial for safeguarding sensitive information transmitted within WSNs. Although data attribution techniques at the base station show promise in providing critical attributes to sensory data and evaluating data reliability, there is still a significant challenge in developing comprehensive security mechanisms that can effectively combat the diverse range of threats faced by WSNs.

The need for a robust security solution is evident in order to address the limitations and vulnerabilities of current security measures and mitigate the risks posed by malicious activities within WSNs.
