You don't show your ID to a TTP you show a homomorphic function of your ID which doesn't leak your credentials and you have a second homomorphic function in the website to the TTP which doesn't leak what your verifying against. 2 and 3 are correct but 1 isn't. They don't get to hold reusable credentials about you, only a function in them which can be verified to show you hold the identity. |
