    one time pad breakable debate

    one time pad breakable debate

    conversation moved to general discussion. since one time pad discussion is not part of the contest thread. it should have its own thread.

    if it can be done. then it can be undone. simple mathematics referring to the one time pad. brute force from a-z for example a character only a-z one time pad is where the debate is. that may be guess work to the actual message. once the message is exposed it is broken. much better to do with a copy of the key for a reassured confident claim of undoing a one time pad. sure.

    i understand clearly what you are saying. too many alternative words show up that have nothing to do with the key or the message text.

    'cannot see the wood for the trees'
    by the same token
    The main problem concerning the use of a one time pad is key management: the key material must be established in advance over a secure channel, be sufficient for all secure communication until new key material can be established, and then only ever used once.
    a secure channel ? you can not know for sure ever if the channel is secure. an assumption of reasonable security is made.

    as said already the message exposed along with other words that also make sense that have nothing to do with the key or message when exposed are different than jumbled text that do not make a word. at least with the exposed words you have a place to start applying external intel to what you have to see what fits or makes the most sense as to which message was the real one encrypted. one time pads are breakable. <crash sound>
