Discrete Mathematics - RSA Algorithm and Mod These are problems concerning the RSA algorithm and Modulo. A. In RSA, suppose bob chooses p = 3 and q = 43. Determine one correct value of the public exponent e, your choice should be the smallest positive integer that is greater than 1. Justify your answer. B. For the e's value you chose above, compute the corresponding secret exponent d. Show your work. C. Compute 540Mod13 D. Compute 5-1Mod11

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,...

Question1: Alice and Bob use the Diffie–Hellman key exchange technique with a common prime q = 1 5 7 and a primitive root a = 5. a. If Alice has a private key XA = 15, find her public key YA. b. If Bob has a private key XB = 27, find his public key YB. c. What is the shared secret key between Alice and Bob? Question2: Alice and Bob use the Diffie-Hellman key exchange technique with a common...

Problem 6.2 In this problem, we will look at a simple application of probability to cryptog raphy. Alice would like to communicate a message to Bob but does not want Eve to learn the message. The difficulty is that Eve can hear everything that Alice says. However, Alice and Bob both have access to a shared random key, which will allow Alice to hide the message from Eve. The block diagram below should help you visualize the scenario. We've kept...
