Technically the mssim protocol is the standard, being part of the
reference implementation, but practically it's terrible: Using two
ports per vTPM is hardly scalable in a cloud situation and, as you say,
it has no security. Ideally someone with TCG connections would try to
standardize a more scalable network server protocol, something nicely
rest based that identified the vTPM by say its EK name.
