 1. What attack is the Diffie-Hellman key exchange vulnerable to?
 
-Man in the Middle attacks
+Man in the Middle
 
 2. What measures can be taken to prevent this type of attack?
 
-RSA Encryption
+Encryption, Authentication over QR code or 2Factor-Authentication
 
 3. For the Diffie-Hellman, a generator g is used. Explain what a generator is and how can it be found
 
 4. Show why for the primes 61,23 and the public key e=60 no private key d can be found
