Problems solved by technology

[0026] However, since the INR route authorization verification mechanism and the BGPSEC technology are implemented at the same time, there will be a lot of pressure on network equipment changes and network performance. Therefore, there is currently no solution that can simultaneously perform BGP route source verification and BGP route path verification.

Embodiment 1

[0074] Embodiment 1: The value of ROA can be embedded into the path attribute.

Embodiment 2

[0075] Embodiment 2: The BGP message can be extended, and a new option is added behind the network layer reachability information, which is used to store the value of ROA. The specific format is as follows:

[0076]

[0077] 1) The originating router sends update+roa;

[0078] 2) The second hop uses ROA to verify UPDATE;

[0079] Y: Forward update, no ROA is required, plus policycert;

[0080] N: Discard;

[0081] 3) The next-hop router directly trusts the previous hop;

[0082] Path validation is based on policycert.

Abstract

The invention discloses a route origin and path two-factor authentication method. The method comprises the following steps that: (1) a source autonomous system AS<1> embeds a route origin authorization (ROA) certificate of the autonomous system AS<1> into a border gateway protocol (BGP) route update message, and sends the update message to a next-hop autonomous system AS<2>; (2) the autonomous system AS<2> verifies the ROA certificate of the AS<1>, and issues a certificate ASPolicyCert, signs the issued certificate ASPolicyCert with a private key, embeds the signed certificate ASPolicyCert into a BGP route update message of the AS<2>, and sends the update message to a next-hop autonomous system AS after a route origin being the AS<1> is verified; and (3) after reception of the update message sent by a last-hop autonomous system, each autonomous system AS acquires the ROA certificate of the AS<1> from the update message, issues a certificate and signs the certificate after the route origin being the AS<1> and a routing path being correct are verified, embeds the certificate into a BGP route update message of the AS, and sends the update message to a next-hop autonomous system till a destination autonomous system AS.

Description

technical field [0001] The invention relates to a method for realizing double authentication of routing source authentication and path authentication, and belongs to the field of network technology. Background technique [0002] As an important infrastructure to ensure Internet interconnection, the inter-domain routing system has a vital impact on the security and stability of the Internet. Because the BGP protocol adopted by the traditional inter-domain routing system lacks the verification of the authenticity of the routing advertisement content, deliberate attacks by hackers and wrong network parameter configurations may lead to route hijacking. Route hijacking has a great impact on the normal operation of the Internet, and may cause a large area of ​​network paralysis. Typical router hijacking incidents that have been reported in the newspapers include: the AS7007 incident in April 1997, the Turkey TTNet router hijacking incident in December 2004, the Con-Edison router ...
