An developer designs, implements, and maintains Internet Key Exchange version () protocols. These protocols play a critical role in creating secure VPN tunnels for data transmission. Their tasks involve creating secure authentication methods, managing cryptographic keys, ensuring the integrity and confidentiality of data, and troubleshooting any issues related to these protocols. They often work closely with network engineers to integrate protocols into larger network systems. Their goal is to ensure secure, reliable, and efficient data transmission across networks, often requiring knowledge in cryptography, network security, and programming languages like C or C++.
