An Internet Protocol version 4/Internet Protocol version 6 (IPv4/IPv6) integrated network system includes at least one first node for creating identification information capable of identifying each secret key shared with at least one second node, and for exchanging the created identification information with each second node in a secure negotiating process. Each second node creates identification information capable of identifying each secret key shared with each first node, and performs the secure negotiating process based on the secret keys corresponding to the identification information exchanged through the secure negotiating process. Thereby, secure communication complying with Security Architecture for the Internet Protocol (IPSec) can be implemented based on the secret keys in the IPv4/IPv6 integrated network system of a Network Address Translation-Protocol Translation (NAT-PT) environment.
