Abstract
A network node selectively encrypts messages between a user plane node and a control plane node in a network system. The user plane node and the control plane node negotiate a connection and indicate an encryption level for the connection. The encryption level is selected from an Information Element (IE) level, a message level, or a feature level. The user plane node and the control plane node selectively encrypt at least a portion of the messages between the user plane node and the control plane node based on the encryption level for the connection.
