(c) Why are most modern symmetric algorithm block ciphers?
(d) Describe four weaknesses of symmetric cryptography.
(e) Consider that Alice have to send bulk data to a remote user Bob.

Assume that the RSA problem is hard, prove that the RSA encryption is secure against IND- CPA. Provide a game between an adversary A and a simulator (or challenger) B.
(a) An opponent is using RSA with the public key {e=53, n=77}. You intercept the ciphertext C=10. (All values on this problem, including the ciphertext and the cleartext, are nume
