Embodiment Construction

[0074] Next, an embodiment of the present invention will be described with reference to the drawings. figure 1 It is a block diagram showing the structure of a network according to IPsec (Internet Protocol Security Protocol) consistent with an embodiment of the present invention. figure 1 In the network according to the embodiment of the present invention, a plurality of IPsec processing devices 2a to 2f are connected to each other via the Internet 100, these IPsec processing devices will communicate with each other to which IPsec is applied, and the IPsec setting server 1 is also connected to 100 on the Internet. Attention, such as figure 1 As shown, the IPsec processing devices 2a to 2f may be routers that provide exchanges between the private networks 201 to 204 by communication based on IPsec. Alternatively, the IPsec processing devices 2a to 2f may be individuals who apply IPsec to their own communications computer.

[0075] figure 2 Is showing figure 1 A block diagram of th...

Abstract

There is provided an IPsec setting server apparatus capable of preventing inconsistency of setting among communicating apparatuses. An IPsec processing section subjects a data communication packet received from an interface section to IPsec processing. An SPD is referred to from the IPsec processing section and records policies for applying the IPsec. An SAD is referred to from the IPsec processing section and records an SA necessary for subjecting an individual kind of communication to the IPsec processing. A request processing section receives a setting request message from the IPsec processing apparatus and returns a distribution message. IPsec policies necessary for determining a requested setting are stored in a distribution policy storage section. Information on respective kinds of SA communication requested to be set is stored in a management table.

Description

Technical field [0001] The present invention relates to a network, an IPsec setting server device, an IPsec processing device, and an IPsec setting method used therefor, and more specifically, to a network structure according to IPsec (Internet Protocol security protocol, Internet Protocol Security Protocol). Provides multiple functions such as confidentiality, integrity and authentication on the Internet. Background technique [0002] Generally, as the Internet spreads widely, there is an increasing need to ensure security on the Internet. Specifically, many companies hope to establish a virtual private network on the Internet at low cost, and establish a network connecting remote offices or similar objects, rather than using expensive private lines to build the network. [0003] In response to this demand, IETF (Internet Engineering Task Force, Internet Engineering Task Force) standardized IPsec (Internet Protocol Security Protocol), which provides a variety of functions, such a...
