Abstract
A centralized challenge response verification server such as a RADIUS server is used to generate challenge responses as well as to verify challenge responses. In this way, the requirement for all machines to maintain a set of shared secrets corresponding to all potential peers is eliminated. In an embodiment of the invention, an authentication plug-in extends the RADIUS server to accept a challenge from an authenticatee and to generate a response to that challenge. The RADIUS server also acts to accept a challenge response and to verify that response. In an embodiment of the invention, a name service server maintains information regarding the network, and may also maintain an identification of network zones and storage profiles within which devices may intercommunicate or other network information.
