Claim 25:
26. The network device of claim 23, wherein when the SA is an IKE SA, the first rekey request is a CREATE_CHILD_SA request for rekeying the IKE SA, the CREATE_CHILD_SA request carries a SA payload which carries the first SPI and the cryptographic suite associated with the first network device, and the first rekey response is a CREATE_CHILD_SA response for rekeying the IKE SA, the CREATE_CHILD_SA response carries a NEW_SPI notification payload carrying the second SPI or carries a Lightweight SA payload carrying the second SPI; and
wherein when the SA is an IPSec SA which is a child SA of the IKE SA, the first rekey request is the CREATE_CHILD_SA request for rekeying the child SA, the CREATE_CHILD_SA request carries a SA payload which carries the first SPI and the cryptographic suite associated with the first network device, and the first rekey response is the CREATE_CHILD_SA response for rekeying the child SA, the CREATE_CHILD_SA response carries the NEW_SPI notification payload carrying the second SPI or carries the Lightweight SA payload carrying the second SPI.
