Q5: Based on RSA algorithm, if the encrypted message value is 707344 and the private key is <86237, 1144987>. Find the value of signed message. (3 Points) Q5: Based on RSA algorithm, if the encrypted message value is 707344 and the private key is . Find the value of signed message. (3 Points)
prime factorization. Assume that zoy wants to send a message to sam. sam generates public and private keys using RSA Encryption algorithm and publishes the public key (n=4717, e=19). zoy has a secret message M to send. Nobody knows the value of M. She encrypts the message M using the public key and sends the encrypted message C=1466 to sam. alex is an intruder who knows RSA and prime factorization well. She captures the encrypted message C=1466. She also has...
your answer. Refer to attack scenarios on mutual authentication protocols that were discussed during the Lecture-7 and Tutorial-7.] 5 Marks] Q5 (OpenSSL and IPFS) Assume that the School of Science of RMIT University is planning to use IPFS-based repository of sensitive files for sharing among staffs. An owner of a particular file, say Alice wants to share the file to her supervisor, say Bob. Therefore, Alice encrypts the file with Alice and Bob's shared AES secret key (KaB) using OpenSSL,...
Bob wants to use the pair (1,143) as an RSA public key. Determine the value of the private key.Encrypt a message M=57. What does this tell you about the security of this public key?
Suppose that Paul wants to use the public RSA value n = 185 and the private key d = 55. What is the value of the public key?
4. Suppose you wish to encrypt the message, M 42 using RSA encryption. Given a public key where p- 23 and q-11 and the relative prime e- 7. Find n, and show all necessary steps to encrypt your message (42). (Hint: check p.411 of the text for information on public key RSA) (5 points)
5.6 Exercise. Describe an RSA Public Key Code System based on the primes and 17. Encode and decode several messages Of coursc, the fun of being a spy is to break codes. So get on your trench coal, pull out your magnifying glass, and begin to spy. The next exercise asks you to break an RSA code and save the world 5.7 Excrcise. You are a secret agent. An evil spy with shallow mumber thery skills uses the RSA Public...
1. Create an RSA private key 2. Output the key in a text format so that it shows the following: modulus public exponent (e) private exponent (d) the primes (p and q) Send me a file called key.txt with this information. 3. Using openssl's rsautl option encrypt this message to me: "NAME" using the public key that's embedded with the private key above. Attach a file named encrypted.txt that contains the encrypted message. Hint: Copy the text above and put...
In each of the following, the two prime numbers p and q, and the message M to be encrypted using RSA are given. For each case, determine the private and public keys and the encrypted message. a) p = 7, q = 11, M = 6 b) p = 11, q = 13, M = 9 c) p = 17, q = 31, M = 5
p=3, q=7 Suppose that Bob wants to create an example of an RSA public-key cryptosystem by using the two primes p ??? and q ???. He chooses public encryption key e He was further supposed to compute the private decryption key d such that ed 1 mod A(pq)). However, he confuses A and and computes instead d' such that ed' =1 (mod P(pq)). (i) Prove that d' works as a decryption key, even though it is not necessarily the same...
