1. A method for accomplishing distributed prefix signing Border Gateway Protocol (BGP) security, comprising:
generating a signature for a new prefix announcement by a processor in a first peer component of a network;
including, by the processor, the signature in a transitive BGP attribute of the new prefix announcement; and
sending, by the processor, the new prefix announcement that includes the transitive BGP attribute that includes the signature to a second peer component of the network.
