Two points. One) Can you please provide technical citations to support this? OTP and PKI are very different technology, and the only way I can make sense of your statement is to guess that the OTP is actually a one-time-password (not a one-time pad) used to initialize the user's PKI account. Two) If the server is leaking data the user authentication is rendered pretty much irrelevant - and PKI with a one-time initialization code would be used for authentication. PKI may also secure the connection, e.g., using SSL/TLS, but it seems that in this case the server was being most dumb - even if my connection were secured using TLS and the best authentication in the world, it seems I would be able to get your data. Which I am sure you wouldn't want. Nor would you be much mollified by knowing exactly who it was that compromised you.
