Not Reinventing PKI until We Have Something Better

Although X.509-based PKI has some well-known problems, they're being, or can be, addressed. In the past, those problems led to proposals for reinventing PKI based on other technologies. However, none of the proposals provided sufficient additional benefit to gain broad adoption. While there are reasons to change and evolve X.509-based PKI, for the present there are no compelling reasons to reinvent the technology.
