Existence of a reasonably strong cipher that can be executed in your head? Posted: 21 Mar 2018 11:36 AM PDT I have really been pondering on this question for a while (and even had some sketches I designed which are looking pretty bleak so far). Here I'll write a quick post outlining what my thoughts are The motivation The idea is that we assume that all electronic devices are monitored by some undesirable third party (e.g. the FBI), and every point in space is also monitored (via camera for instance) by the FBI (making executing a cipher on a piece of paper useless). Can a cipher with lowered security parameters still be somewhat feasible for a human to compute exist? (It can be very hard - such as keeping 80 bits in your head, but possible with extensive training). The 'threat model' The following is assumed:
Under the above (incomplete for now) the cipher should be secure (indistinguishable from a random function of the input, e.t.c. I don't need to repeat this I'm sure you know what I mean) [link] [comments] |
