The Requirements for Secure Routing


Both ISPs and users have put forward requirements for secure routing, the scenarios are analyzed in the draft draft-chen-secure-routing-use-cases. This draft analyzes the functions required to implement secure routing.

Attack detection and users security requirements translateion are out of scope.

Status of This Memo

This Internet-Draft is submitted in full conformance with the provisions of BCP 78 and BCP 79.

Internet-Drafts are working documents of the Internet Engineering Task Force (IETF). Note that other groups may also distribute working documents as Internet-Drafts. The list of current Internet-Drafts is at

Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as reference material or to cite them other than as "work in progress."

This Internet-Draft will expire on 10 September 2023.

Table of Contents

1. Introduction

Starting from the requirements of network operators and users, it is necessary to take the security attribute as the key factor to select the route and transmission path to measure the link transmission security. To achieve this goal, the following contents need to be studied.

  1. Static node security, by appraising the trustworthiness;
  2. Expression of node security capability, by YANG Model;
  3. Type of security functions: reorganize and define the security functions supported by existing network devices, and encode them, such as security monitoring, traffic filtering. Generally, the security functions of a device can be described as a collection.
  4. Protocol for collecting node security capabilities, such as adding new parameters to BGP-LS;
  5. A protocol for distributing security policy configuration, by SRv6;

2. Requirements for Secure Routing

2.2. Expression of security capability

YANG model is used to describe the security capability of nodes, such as security service type and remaining capacity.

2.3. Type of security functions

Fine-grained security functions, more detail in draft draft-chen-atomized-security-functions.

2.4. Node security capability collection protocol

Collect the security capabilities of all nodes in the network through BGP-LS, more detail in draft draft-chen-idr-bgp-ls-security-capability.

2.5. Distribution of security policy

Security policies can be distributed through extended SRv6 SRH.

3. IANA Considerations

This memo includes no request to IANA.

4. Security Considerations
