Exercise 9.9.1: Breaking RSA by factoring.

Bob publishes his public key (e, N) = (109, 221)

(a)

Show that if Eve can factor N (N = 13 · 17), then she can determine Bob's private key d. What is Bob's private key?

(b)

Now suppose that Eve intercepts the message 97. Use Bob's private key to decrypt the message.

In the RSA cryptosystem, Alice’s public key (N, e) is available to everyone. Suppose that her private key d is compromised and becomes known to Eve. Show that if e = 3 (a common choice) then Eve can efficiently factor N.

In the RSA public-key encryption scheme, each user has a public key, e, and a private key, d. Suppose Alice leaks her private key. Rather than generating a new modulus, she decides to generate a new public key and a new private key. Is this safe? why or why not?

7. Suppose Bob has the public key (n, e) = (21733, 691). You are Eve, and you have intercepted the ciphertext C = 21012. On a whim, you decide to check whether C and n are relatively prime, and to your delight, you discover that they are not! Show how you can use this to recover the plaintext M. Note: The chance that M (or equivalently C) is not relatively prime to the modulus n is1/p + 1 /q− 1/pq...

We are working on Public Key Crypto, RSA, Extended Euclidean algo Let n = 2419 = 41 ∗ 59 and e = 7. (1) Find the private key d. (2) Encrypt the message 6. (3) Sign the message 10. Assume RSA is used. Use the egcd.py program at the lecture attachments folder, described in section 10.3.3, to compute d. For parts 2 and 3, you only need to show the formula; there is no need to calculate the final results....

Suppose Alice and Bob have RSA public keys in a file on a server. They communicate regularly, using authenticated, confidential message. Eve wants to read the messages but is unable to crack the RSA private keys of Alice and Bob. However, she is able to break into the server and alter the file containing Alice’s and Bob’s public keys. (1) How should Eve alter the file to so that she can read confidential messages sent between Alice and Bob, and...

Alice wants to send a plaintext message m = 10 to Bob secretly using RSA public key cryptosystem. Bob selects p = 7, and q = 13 with e = 5. You have to perform following tasks: a. Compute and list Bob’s public and private keys. b. Compute the ciphertext that Alice will send to Bob using plaintext message m = 10. c. Recover the actual plaintext from the ciphertext sent by Alice

it is a question of discrete math RSA is the most widely used public key cryptosystem. In this discussion, you will apply RSA to post and read messages. For this reflection discussion, use the prime numbers p = 3 and q = 11. Using the public key e = 3, post a phrase about something that you found interesting or relevant in this course. Include only letters and spaces in your phrase. Represent the letters A through Z by using...
