Abstract
A system for managing security keys in a wireless network includes a manufacturer certification authority (MCA) for providing a signed digital MCA certificate for installation into a new network element (NE) at the manufacturer's facility prior to the new NE being installed and initialized in the network. The MCA also provides a source of trusted authority for authenticating legacy NEs in the network. The system includes a service provider certification authority for managing certificates and files used by the NEs to communicate securely within the network, a signing server for providing signing services to NEs for authentication, an element manager for providing security key and digital certificate management, and a management agent (MA) for providing proxy functionality of the EM security key services to NEs not directly connected to the EM.
