Assuming that someone is able to telepathically intercept thoughts and words in my mind, what mechanism will allow me to authenticate securely? A solution that does not yield to physical search or subpoena is welcomed but not necessary.
So for example, a
/dev/random generated file on a pendrive is one solution (unless seized, but that isn't a passive attack), fingerprint reader is another (unless ordered by say court, also hard to duplicate without the person). Any other ideas?
Yes, this is a legitimate question. It is not quantum cryptography but please take this seriously.
