SensorNet-Cipher: A Lightweight Protocol for Security in Resource-Limited Networks

The novel cryptographic protocol presented in this research paper is specifically designed for wireless sensor networks (WSNs), which are generally limited in terms of computational power, energy, and the requirement for strong security. In order to overcome these limitations and offer high-level security against a variety of cyberthreats that are typical in WSNs, this study presents SensorNet-Cipher, a novel symmetric key encryption system. The protocol places a strong emphasis on lightweight architecture, requiring the least amount of processing power to carry out encryption and decryption operations. Effective key generation, distribution, and management techniques that are specially adapted for the dynamic and distributed nature of WSN s are important aspects. The use of 128-bit and 256-bit key sizes is covered in the study to provide robust encryption without putting too much strain on the sensor nodes. In order to ensure data integrity and source authenticity, SensorNet Cipher also includes an advanced integrity and authentication mechanism that makes use of an optimized Message Authentication Code (MAC). The protocol is specifically made to be energy-efficient, which is important for extending the life of sensor nodes. SensorNet Cipher's resilience against common security risks, such as replay and man-in-the-middle attacks, is demonstrated by complete security analysis. We also examine how well the protocol scales and adapts to different network topologies and sizes. This work makes a substantial contribution to the field of network security by providing a workable security solution for situations with restricted resources, such WSNs.
