Abstract Abstract
This document defines a standard profile for X.509 certificates for This document defines a standard profile for X.509 certificates for
the purposes of supporting validation of Autonomous System (AS) paths the purposes of supporting validation of Autonomous System (AS) paths
in the Border Gateway Protocol (BGP), as part of an extension to that in the Border Gateway Protocol (BGP), as part of an extension to that
protocol known as BGPSEC. BGP is a critical component for the proper protocol known as BGPsec. BGP is a critical component for the proper
operation of the Internet as a whole. The BGPSEC protocol is under operation of the Internet as a whole. The BGPsec protocol is under
development as a component to address the requirement to provide development as a component to address the requirement to provide
security for the BGP protocol. The goal of BGPSEC is to design a security for the BGP protocol. The goal of BGPsec is to design a
protocol for full AS path validation based on the use of strong protocol for full AS path validation based on the use of strong
cryptographic primitives. The end-entity (EE) certificates specified cryptographic primitives. The end-entity (EE) certificates specified
