Which of the following are important differences between digital signatures and message authentication codes (MACs)? (Choose all that apply.) a. MACs can accept messages of arbitrary length, while digital signatures are limited to messages with sizes less than the RSA modulus b. Digital signatures can be used to calculate a signature on the encrypted message, but MACs can only be used on the plaintext message before encrypting c. Digital signatures can enforce integrity, authenticity, and non-repudiation, but MACs can only...

Consider the following scenario: Alice receives a message, a digital signature and a certificate from Bob. In order to verify the signature, Alice does the following: Hashes the received message using the same hash algorithm that Bob used, that's your calculated hash Decrypts the signature using the public key contained in the certificate, that your decrypted hash Compares the calculated hash and the decrypted hash Because the 2 hashes are identical, Alice goes on and: Checks the validity period on...
