The Twofish Secure Routing Protocol (TSRP) makes wireless sensor networks (WSNs) safe from wormhole attacks by using the Twofish encryption method. This setup uses a special type of encryption to protect data as it moves across networks. TSRP adjusts how data is routed for better security and uses a smart system to manage encryption keys. It starts with spreading encryption keys throughout the network, finds secure paths for data using encrypted messages, and keeps a close watch on the routes to prevent attacks. TSRP is proven to be better because it uses less energy, delivers more data successfully, moves data faster, and reduces waiting time. This shows Twofish is a strong tool for keeping sensor networks safe and working well.
