Descripción
Resumen:	With the rapid evolution of network technologies, ensuring secure and efficient data transmission has become a critical challenge, especially with the increasing adoption of Software-Defined Networking (SDN). Traditional network architectures struggle to address security threats such as data breaches, unauthorized access, and control-plane attacks. SDN, while offering centralized control and programmability, also introduces vulnerabilities that can be exploited by malicious actors. This research focuses on designing and implementing a secure data transmission framework that integrates SDN with advanced cryptographic techniques to mitigate these security risks. The proposed framework employs AES-256 encryption for data confidentiality, Diffie-Hellman (DH) key exchange for secure key distribution, and Transport Layer Security (TLS) for securing control-plane communication. Unlike existing approaches, this multi-layered security model enhances network resilience while maintaining optimal performance. The methodology involves developing an SDN-based network environment using the Ryu controller and Mininet emulator, implementing encryption mechanisms, and evaluating key performance metrics such as packet delivery rate, latency, and resource utilization. Experimental results demonstrate a 100% packet delivery rate, no packet loss, and an average latency of 3-5 ms. Despite the slight increase in CPU and memory utilization, the framework effectively balances security and efficiency, making it a robust solution for modern network infrastructures.
