RPKI (Resource Public Key Infrastructure)

RPKI (Resource Public Key Infrastructure) is a security framework that helps verify the authenticity of internet routing information. It ensures that the IP address ranges and network routes announced by organizations are legitimate, preventing malicious or accidental misdirection of internet traffic. RPKI uses digital certificates and cryptographic keys to confirm that a network sender has permission to announce specific IP prefixes, enhancing the overall security and stability of internet communications. Essentially, it's a trusted system that verifies who owns what part of the internet’s address space, reducing routing errors and malicious activities.
