At its core, is a process that verifies a user or device’s identity before granting access to internet resources, using a combination of Key Exchange protocols (like Diffie-Hellman or IKEv2) and Digital Certificates (X.509). Unlike simple password-based logins, KEC-based systems rely on asymmetric cryptography to prevent eavesdropping, replay attacks, and man-in-the-middle (MITM) intrusions. : Requires a unique username (often the Roll
