Ahh, homework.

Alice and Bob needs to exchange a secret key. They use the Diffie-Hellman key exchange.

  • They agree on using a prime number p=937 and g=29936 and ensure that mod(29^936,937)=1
  • Alice choose a secret key a=349
    • Compute A = g^a mod p
  • Similarly Bob chooses his secret key b=773
    • Compute B = g^b mod p
  • Alice sends A to Bob and Bob sends B to Alice over an open line
    • Calculate their shared secret for both Alice, B^a, and Bob, A^b and ensure that they are the same.
  • Why is it difficult to figure out their secret for Eve?

Apart from the exercises coming in a docx format and no matter if I open it in Pages, Textedit and Google Docs numbers are still screwy and not showing up, who is hell Eve?
