Embodiment Construction

[0052] Hereinafter, a secure communication system and method of an Internet Protocol version 4 / Internet Protocol version 6 (IPv4 / IPv6) integrated network system will be described in detail with reference to the accompanying drawings.

[0053] FIG. 1 is a structural block diagram of an IPv4 / IPv6 integrated network according to an exemplary embodiment of the present invention.

[0054] Referring to FIG. 1 , a plurality of IPv6 nodes 100 included in an IPv6 network and an IPv4 node 300 included in an IPv4 network are connected through a Network Address Translation-Protocol Translation (NAT-PT) server 200 .

[0055] The NAT-PT server 200 is located on the boundary between the IPv4 network and the IPv6 network, and based on the IPv4 address pool (not shown), dynamically allocates the IPv4 address to the IPv6 node 100, in the IPv4 address pool, when initiating a session IPv4 addresses to be dynamically allocated to IPv6 nodes 100 are collected.

[0056] A case where secure communic...

Abstract

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.

Description

technical field [0001] The present invention relates to a secure communication system and method for an Internet Protocol Version 4 / Internet Protocol Version 6 (IPv4 / IPv6) integrated network system. Background technique [0002] The Internet occupies a fixed place as the core infrastructure of the information society. Due to the high-quality development of real-time services (such as Voice over Internet Protocol (VoIP) and Internet Television (TV)), services exchanged over the Internet have evolved from services containing text information to services containing voice information, image information, and video information. Multimedia services, as well as business volumes, show a trend of explosive growth. [0003] The currently established Internet based on Internet Protocol Version 4 (IPv4) adopts small pieces of address information and complex header structures to adapt to fast-growing nodes and services. For this reason, the service processing speed of routers and nodes ...
