RPKI : Resource Public Key Infrastructure

Posted on by lechuck park

From Claude with some prompting
RPKI (Resource Public Key Infrastructure) Overview

  1. Background of RPKI Need

1.1. Internet requires reliable IP management

1.2. Traditional IP address and routing system vulnerabilities

1.3. Need for secure and verifiable routing infrastructure

  1. Core Components of RPKI Structure

2.1. IANA (Internet Assigned Numbers Authority)

  • Top-level authority for IP resource management
  • Oversees global IP address allocation
  • Delegates authority to regional registries

2.2. RIR (Regional Internet Registry)

  • Manages continental-level resources
  • Key organizations: ARIN, RIPE NCC, APNIC, LACNIC, AFRINIC
  • Handles certification management

2.3. NIR (National Internet Registry)

  • National-level IP resource management
  • Works under RIR guidance
  • Manages local resource allocation
  1. RPKI Operational Process

3.1. Resource Management

  • IP addresses grouped by ASN (Autonomous System Number)
  • Systematic management to prevent chaos
  • Certificate-based validation system

3.2. Technical Implementation

  • Caching servers for RPKI data
  • Router configuration using BGP
  • Real-time validation of routing information
  1. Security Features

4.1. BGP Route Protection

  • Prevents BGP hijacking attempts
  • Validates peer BGP advertisements
  • Ensures routing path integrity

4.2. Validation States

  • OK: Valid route
  • NOT FOUND: No RPKI record
  • INVALID: Failed validation
  1. Benefits of RPKI

5.1. Enhanced routing security

5.2. Prevents unauthorized IP address use

5.3. Provides verifiable trust chain

5.4. Maintains internet routing stability

Summary

This RPKI-centric structure transforms traditional IP management into a robust, secure, and verifiable system for global internet routing infrastructure.

The system essentially creates a chain of trust from IANA through RIRs and NIRs down to individual network operators, ensuring the legitimacy of IP address usage and routing announcements.
