An initiating device: generates a message having an ISAKMP-based header that includes a security parameter index (SPI) field; identifies a key in the SPI field of the ISKMP-based header; and sends the message to a responding device. The responding device: receives the message; extracts the key identifier; and when a shared key is selected using the key identifier, uses the selected shared key to establish, with the initiating device, a session having a secure tunnel.
