Question 29 1 pts In an application of the RSA cryptosystem, Bob selects positive integers p, q, e, and d, where p and a are prime. He publishes public key (e, N), where N =p'q. the number d is the decryption key. 0 = (p-1)(q-1). Select all the statements that are correct. Ifm is not equal to por q, then (m) mod N=m It must be the case that d'e mod 0 - 1 If mis not equal to por...
1. For n-pg, where p and q are distinct odd primes, define (p-1)(q-1) λ(n) gcd(-1-1.411) Suppose that we modify the RSA cryptosystem by requiring that ed 1 mod X(n). a. Prove that encryption and decryption are still inverse operations in this modified cryptosystem. RSA cryptosystem.
2. Alice is a student in CSE20. Having learned about the RSA cryptosystem in class, she decides to set-up her own public key as follows. She chooses the primes p=563 and q = 383, so that the modulus is N = 21 5629. She also chooses the encryption key e-49. She posts the num- bers N = 215629 and e-49 to her website. Bob, who is in love with Alice, desires to send her messages every hour. To do so,...
In a RSA cryptosystem, a participant A uses two prime numbers p = 13 and q = 17 to generate her public and private keys. If the public key of A is 35, then the private key of A is 11. Alice wants to encrypt a message to Bob by using the RSA algorithm and using keys in (A) The plaintext = “HI”. Answer: _______________

Bob chooses 7 and 11 as p and q prime numbers. Now he chooses two exponents e to be 13, then d is 37. Note e * d mod 60 = 1 i.e. they are inverse to each other. Now imagine that Alice wants to send the plaintext 5 to Bob. She uses RSA algorithm to encrypt the message (perform encryption). Also, show your work how Bob perform decryption operation in order to extract plaintext. PLEASE SHOW ALL WORK AND...
