I disagree. The MITM is foiled by one successful communication.
I'm going to need some clarification of this; what is meant by "successful"? If you mean "a communication without a MITM participating", and presuming also that that communication would involve a key validation, then I suppose it's true. However, I don't see how this success can be evaluated if the parties do not have nearly complete control over the communications substrate. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | Nobody's going to listen to you if you just | Mike McNally (m5@tivoli.com) | | stand there and flap your arms like a fish. | Tivoli Systems, Austin TX | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
