Secure Sessions

Secure Sessions provide a way to password-protect communication between two nodes on a network above and beyond the security of the network itself. With secure sessions, a device can 'log in', or create a session with another device that is encrypted and only readable by the two nodes involved. By restricting certain actions—such as remote AT commands or FOTA updates—to only be allowed over one of these secure sessions, you can make it so access to the network does not allow network configuration. A password must be set and the proper bits of SA (Secure Access) must be set to enable this feature.

The following definitions relate to secure Sessions:
