Joe, a user, wants to send Ann, another user, a confidential document electronically. Which of the following should Joe do to ensure the document is protected from eavesdropping?
- A. Encrypt it with Joe's private key
- B. Encrypt it with Joe's public key
- C. Encrypt it with Ann's private key
- D. Encrypt it with Ann's public key
Homework Answers
Ans: D.Encrypt it with Ann's public key,
the sender has to encrypt the document with receiver's public key, on receiver end it is decrypted by his private key, this way no other who is in between can view the content, thus protecting it from eavesdropping.

The Diffie-Hellman public-key encryption algorithm is an alternative key exchange algorithm that is used by protocols such as IPSec for communicating parties to agree on a shared key. The DH algorithm makes use of a large prime number p and another large number, g that is less than p. Both p and g are made public (so that an attacker would know them). In DH, Alice and Bob each independently choose secret keys, ?? and ??, respectively. Alice then computes...

Discrete Math 1. Use the primes P1 = 3 and P2 = 17 and the value E = 3 with the RSA algorithm to compute the values below needed to get the keys: What is the value of N? What is the value of Z? What is the value of D? (ABET 5) Using the values from the problem 9) above, show how to encrypt the message, M = 44. Do NOT simplify, just show the computation needed to encrypt...
