Abstract

Techniques for selecting authentication roles when establishing a link between devices in a secure network are provided. By assigning role levels to devices, devices may be more likely to assume a preferred role when establishing a link. For example, during a negotiation process, each device may establish a timer value based on their role level. Each device may initiate a timer with the timer value and, the device whose timer value expires first may assume a role as authenticator.
