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. James
