The exponents of RSA should not be e = 1 nor e = 2. Why?
Please prove your analysis.
(16 pts) In the RSA public key cryptography system (S,N,e,d,E,D), let p = 347, q = 743, and N = 347 · 743 = 247821. (a) (8 pts) Which of the two numbers 4193, 4199 can be an encryption key, and why? If one of them can be an encryption key e, find its corresponding decryption key d. (b) (8 pts) How many possible pairs (e,d) of encryption and decryption keys can be made for the RSA system? (If you...
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...
Using RSA Implementation:
1. Alice's RSA public key is given by (e, n) = (59, 1189). = (a) Determine Alice's private key (d, n). (b) Bob sends his first message Mi 67 to Alice, encrypting it with RSA using Alice's public key. He obtains a cypher text Cị that gets forwarded to Alice. What is Cį? (c) Bob sends his second message M2 to Alice, encrypting it with RSA using Alice's public key. Eve, who was eavesdropping on the commu-...
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
1. the reason to use logarithms is A. The constant e has unknown exponents B.To divide the population by t C the constant g has variable exponents Dto take the difference of N0 and Nt E The constant e has to be determined 2. the logarithm A IS taken on one side so that the exponents can be equal to Nt B is used to determine the difference of N0 and Nt C is used to calculate e D Enable...
please solve soon
e the equation so that it is in form 1, if possible. If it is not possible to put it in form 1, then put it in form 2, and find ef P()dx form 1: vvdy w(x)dx form 2: dx +Poy-) The symbols a, b and c are nonzero constants Your final answer must have like terms combined and fractions reduced. Also, your final answer is to have as few exponents as possible. (An exponent that has...
Exercise 1 (2 pts). In an RSA cryptosystem, Bob's public key is (n = 253, e = 3), Alice uses this public key to encrypt a message M for Bob. The resulting ciphertext is 110. Recover the message M. (You can use online modular calculators available at the Web.)
Exercise 1 (2 pts). Alice has her RSA public key (n,e) where n = 247 = 13·19 and e = 25. What is her secret key and what is her signature corresponding to the message M = 63? n=247=13 x 19
