Abstract
Various embodiments include a method for managing a group of devices in communication with each other and sharing a set of keys. The method may include opening a secure channel with each of two devices from the group; providing the set of keys to the two devices from the group, wherein the set of keys include an encryption and an authentication key; indicating to the two devices to begin using the set of keys; and performing an audit process including verifying that nodes within a key group have the same copy of encryption and authentication keys. Embodiments of the method may include synchronization, active/standby redundancy and the ability to manage the network when some nodes perform the data encryption and some node do not, do, or when both encrypted and non-encrypted tunnels and services can work together.
