RPKI not implemented

Border Gateway Protocol (BGP) is the postal service of the Internet. It’s responsible for looking at all of the available paths that data could travel and picking the best route.

Unfortunately, it isn’t secure, and there have been some major Internet disruptions as a result. But fortunately there is a way to make it secure.

ISPs and other major Internet players (Comcast, Sprint, Verizon, and others) would need to implement a certification system, called RPKI. I just checked and Cox has not implemented this protocol. When will this happen so our internet will be secure?
