Question 1.
What is the purpose of the public key in RSA?
Show hintHide hint
Think about how public and private keys function in encryption.
Question 2.
What does the modulus N represent in RSA?
Show hintHide hint
Recall the definition of N and its components.
3Question 3.
What does the RSA algorithm primarily rely on for security?
- Symmetric Key Length
- Hard Factoring of Large Numbers
- Digital Signatures
Show hintHide hint
Think about what makes RSA secure against attacks.
4Question 4.
True or False: The public key can be easily shared without compromising security.
- True
- False
Show hintHide hint
Recall the difference between public and private key functionalities.
Question 5.
You are given the public key (N = 221, e = 15) and a ciphertext (c = 38). Calculate the original message m assuming it was encrypted with the RSA algorithm.
Show hintHide hint
Focus on factoring N first and then use the steps of RSA.
Question 6.
Create an RSA scenario with your chosen large primes: p = 61, q = 53; demonstrate encryption of the message 'Hello' represented as an integer.
Show hintHide hint
Represent the message well and remember to apply the proper RSA formula.
