    Can anyone tell me if diffie hellman is an example of the discrete logarithmic problem.

    I was wondering if anyone has any knowledge in this area. I'm trying to understand the mathematical principle behind Diffie Hellman and the use of primitive roots.

    There is an example where it says. calculate y = 10(^97)Mod 89.

    10 = 10 Mod 89
    10^2 = 11 Mod 89
    10^4 = 32 Mod 89
    10^8 = 32 Mod 89
    10^16 = 45 Mod 89
    10^64 = 8 Mod 89

    Therefore
    10^97 Mod 89
    = 10^64.10^32.10.Mod 89
    = 8^39^10.Mod 89
    = 5
    I have no idea what this is about!!

    Could anyone show me a way of going about doing an example where it says take a prime numer 11 and another number 3 which may be published. Use them to illustrate the diffie hellman method?

    I'm lost!
