What security protocol uses IKE for key management?

The security protocol that uses Internet Key Exchange (IKE) for key management is IPSec. IKE is a framework that facilitates the secure exchange of cryptographic keys and their management, which is essential for establishing secure IPSec tunnels. IPSec is used to provide confidentiality, integrity, and authentication for data traffic over IP networks.

This protocol relies heavily on IKE to negotiate security associations and to determine which cryptographic algorithms and keys will be used. The ability of IKE to provide secure key exchanges in an automated manner is one of its significant advantages, allowing for dynamic configuration of the security parameters necessary for creating secure communications.

Other options, such as L2TP, SSL/TLS, and SSH, utilize different methods and protocols for key management that do not involve IKE. For instance, SSL/TLS relies on public key infrastructure for establishing secure connections, while SSH uses its own methods for key management and does not rely on IKE.
