The U.S. Department of Homeland Security has spent $3 million over the past few years on research aimed at bolstering the security of the Internet's routing system. Now, as this research is being deployed across the Internet, DHS wants government agencies and their carriers to be among the earliest adopters of the new Resource Public Key Infrastructure (RPKI) system that it helped create.
DHS considers the RPKI system to be a much-needed first step in securing the Internet's core routing protocol, which is called the Border Gateway Protocol (BGP). In addition to its support of RPKI, DHS also has spent around $1 million on research and software development aimed at adding security directly to BGP.
