And how can that happen in such a way that an application listening to
the incoming information can't get at it first?


It can't, but protecting pieces of memory from prying eyes was what this discussion was about. If the key to decrypt the incoming message is stored in a secure manner (and deleted securely once the transaction is over), there is no way the eavesdropper can read it (always assuming the encryption algorithm is sound). This is more or less why encryption was invented, in case anyone hasn't done their homework. If you take encryption out of the mix there's no way to protect the data.
