Abstract
System and methods are provided for admission in a network comprising at least one node providing network controller (NC) functionality. A first node in the network, which is capable of generating SALTs, may assume NC functionality, and may distribute the SALT to at least one other node within the network. The first node may receive from the at least one other node, during admission to the network, a request for a dynamic encryption key, with the request being encrypted using a static encryption key unique to the at least one other node, and the static encryption key being determined based on the SALT. The first node may then send a response comprising one or more dynamic encryption keys to the at least one node, for use in network communications, wherein the response is encrypted using a static encryption key
