Abstract:
A method and system for including security information with a packet is disclosed. A packet is detected as it exits a first network and enters a second network. The first network is configured to support a network security technique, and the second network is not configured to support the network security technique. Network security information associated with the network security technique is included with the packet. A network device is configured to include network security information in overhead of a packet. A method for identifying a first network device in a network is also disclosed. Identification information of the first network is communicated to a second network device.

Abstract:
Various systems and method are disclosed for disseminating security server contact information in a network. For example, one method (e.g., performed by a security server) involves determining that a network device is a secure network device, in response to participating in a security exchange with the network device; and then sending a server list to the network device. The server list includes the network address of at least one security server. Another method (e.g., performed by a network device) involves initiating an authentication exchange; receiving a server list, which includes the network address of a security server, as part of the authentication exchange; and communicating with the security server by sending a packet to the network address included in the server list.
Abstract:
Various methods and systems for dynamically determining the role of a network device in a link authentication protocol exchange are disclosed. In one embodiment, such a method involves monitoring several (e.g., two) link authentication protocol exchanges. These link authentication protocol exchanges can be initiated at substantially the same time. A first network device acts as an authenticator in a first one of the link authentication protocol exchanges and a supplicant in a second one of the link authentication protocol exchanges. One of the link authentication protocol exchanges is terminated prior to completion.
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.
