Problems solved by technology

As the RPKI CA system continuously issues, updates or revokes objects, the resulting massive incremental files will pose a huge challenge to the caching infrastructure of the RPKI data warehouse

Embodiment Construction

[0027] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described below through specific embodiments and accompanying drawings.

[0028] The RPKI data warehouse incremental synchronization mechanism of the present invention has three major innovations: 1) adding an "update" element to the incremental file; 2) adding an active notification mechanism; 3) setting up an incremental file monitoring system. Each part is described in detail as follows.

[0029] Step 1: Add an update element to the incremental file

[0030] Depend on image 3 It can be seen that there are only "publish" and "revoke" elements in the current incremental file, and the format of the two elements can be summarized as follows:

[0031] delta_element|=element publish{

Abstract

The invention relates to a RPKI (Resource Public Key Infrastructure) data warehouse incremental synchronization method. The method comprises the following steps: 1) an updating element is added in an incremental file, and for an object file of which the content is partially updated, a RPKI relying party performs data synchronization with the RPKI data warehouse through the updating element; 2) an active informing mechanism is added, when the content in the RPKI data warehouse is changed, a new updating informing file is generated and actively sent to the RPKI relying party, thus, the RPKI relying party is enabled to synchronize the updated file; 3) an incremental file monitoring system is established, wherein the system is used for monitoring acquisition condition of the incremental file and deleting the incremental file which is only acquired by a very small amount of the RPKI relying parties. With the method, caching load of the RPKI data warehouse is reduced, and bandwidth pressure during a data synchronization process is relieved.

Description

technical field [0001] The invention belongs to the fields of information technology and network technology, and in particular relates to an incremental synchronization method for RPKI data warehouses. Background technique [0002] RPKI (Resource Public Key Infrastructure, Internet basic resource public key certificate system) is a public key certificate system used to ensure the safe use of Internet basic code number resources (including IP addresses and AS (Autonomous System) numbers). By extending the X.509 public key certificate, RPKI relies on the resource certificate to realize the authentication of the authorization of Internet basic code number resources, and helps the inter-domain routing system in the form of ROA (Route Origin Authorization, routing source statement) to verify certain Whether an AS's route advertisement for a specific IP address prefix is ​​legal. [0003] In the RPKI system, the allocator of code number resources issues certificates for allocatin...
