Question: Breaking RSA and Elgamal: Try to decrypt the following ciphertexts by factoring the RSA exponent and by solving the DLP in the case of Elgamal.

Breaking RSA and Elgamal: Try to decrypt the following ciphertexts by factoring the RSA exponent and by solving the DLP in the case of Elgamal.  

 


(a) RSA: The parameters are N = 10403, e = 7, and the ciphertext is c = 7288.
(b) Elgamal: The parameters are p = 2027, g = 2, h = 1160 and the ciphertext is (c1, c2) = (1002, 1704).
