The document discusses resource public key infrastructure (RPKI) and APNIC's RPKI service. It provides 3 key points:
1) RPKI uses a PKI architecture to securely associate IP address resources to their holders through cryptographically verified certificates. This improves security of internet routing.
2) APNIC offers an optional RPKI certification service through MyAPNIC where members can generate and manage certificates for their address blocks.
3) The RPKI system is still being developed and tested but offers a way to experiment with generating route origination authorizations (ROAs) to authorize routing of specific address prefixes.
