    only x, y and n need to be very large for this to be secure. g can be small.

  • @achyuthvishwamithra
    @achyuthvishwamithra 10 місяців тому

    It is also a good thing to know that g is a primitive root modulo of n

    There is an issue, what if 'Tom' supposes z=7 then he'll be able to calculate the correct final key i.e. "10" like others do. So if someone chooses/assumes a prime number on his side as well then the game is over LOL ? What's your comment on this CBTVid?

  • @yves4360
    @yves4360 Рік тому

    I'm not sure you need 2 prime numbers to start. A prime number and a generator is normally needed if not mistaken.

    An example of an even higher prime number would be more useful to see and the anology on it. something like n = 101 or something like that and g be like 27

    Great explanation. Now, if Bob wants to send a message to Alice, how does he encrypt it? This may be a dumb question, but I'm not sure where the message fits in here. What am I missing?

  • @babthooka
    @babthooka 5 місяців тому

    Tom's number ( z=4 ) is not prime. Should it not be?

  • @ethanbrehin220
    @ethanbrehin220 6 місяців тому

    But what's the point of getting uncrypting k = 10 on the receiving end ? When and who decided that the uncrypted message would be 10 ?

    How to find the remainder

  • @seabiscuitthechallenger6899

    With the four public numbers and some algebra the key can be uncovered 😈

    But g must be primitive root of n isn't it?

  • @shivrajpatil1612
    @shivrajpatil1612 Рік тому +4

    I had a doubt....why was Tom not able to get the value of K right....he used the same g and n right??

    • @peekaboo6026
      @peekaboo6026 5 місяців тому +2

      Because he used a different Z... He'd get the value right if he could guess the X and Y Alice and Bob were using. but they're private.

    • @sarfarazmasood5547
      @sarfarazmasood5547 Місяць тому

      Becoz in the equations to calculate K, TOM has no idea about x & y as these were never shared on the network

    I think the hacker needs to get the larger exchanged result in this case 10, 2 are obtained and the hacker going to select 10 and can find the secrete key by having his/her own key starting from 7 like 7,11,13,17..... just use the formula as bob and alliance 10pow7,11,13,...., mod 11 is always 10! so, the exchanged key also keep as a secret. the tutorial is so amazing and wonderful!
