Abstract
Systems and methods provide logic for distributing cryptographic keys in a physical network comprising a plurality of physical nodes. In one implementation, a computer-implemented method is provided for distributing cryptographic keys in a physical network. The method includes receiving information mapping a virtual network address of a virtual node to a physical network address of a physical node. The virtual node may be associated with a virtual network hosted by the physical node, and the received mapping information identifies a virtual network address of the node and the physical network address of the node. The mapping service transmits a current version of a cryptographic key and an identifier of the current version to the physical node.
