Enhancing Secure Data Transfer In Wireless Networks Using Onion Routing And Blockchain Technology

The proliferation of cyber-attacks, data breaches, and the disclosure of sensitive information has elevated the issue of secure data transfer via wireless networks to a crucial level of awareness. This research delves at the potential of combining Onion Routing with Blockchain technology to improve the security of wireless data transfer. By encrypting data in layers and routing it through several nodes, Onion Routing provides great anonymity and makes it difficult for attackers to trace the communication channel. By transparently and immutably recording all transactions, Blockchain technology guarantees data integrity and eliminates the possibility of tampering. When used together, these technologies provide an exceptionally safe method of data transmission via wireless networks; this is especially important in industries like healthcare, finance, and government that place a premium on confidentiality and confidentiality of information. We put the system through its paces to see how it handled latency, throughput, packet loss, and power consumption. While there are significant improvements to security, the results show that there are performance trade-offs including higher latency and energy consumption, which might make the system unsuitable for real-time or situations with limited resources.
