+`Authnode` provides a general authentication & authorization service among `CubeFS` nodes. `Client`, `Master`, `Meta` and `Data` node are required to be authenticated and authorized before any resource access in another node.
 
 Initially, each node (`Auth`, `Client`, `Master`, `Meta` or `Data` node) is launched with a secure key which is distributed by a authenticated person (for instance, cluster admin). With a valid key, a node can be identified in `Authnode` service and granted a ticket for resource access.
