Abstract
Systems, methods, and devices of the various embodiments may enable distributed prefix signing by publishing a public key in a Domain Name System (DNS) text record, using a private origination key to generate a signature for a new prefix announcement, including the signature in a transitive Border Gateway Protocol (BGP) attribute of the new prefix announcement, and sending the new prefix announcement to peer components. The peer components may query an address and routing parameter area (ARPA) record to obtain nameserver information for an entity associated with the received prefix announcement in response to determining that the received prefix announcement includes a transitive BGP attribute that includes the signature, retrieve a public key from a Domain Name System (DNS) text record, and determine whether the signature included in the transitive BGP attribute of the received prefix announcement is valid based on the public key retrieved from the DNS text record.
