In cryptography, we assume that both the cryptographic algorithm and key are secret.

Symmetric key encryption is generally slower than public-key encryption

Alice sends Bob a plaintext message M and its digital signature S, signed with Alice’s private key. However, Eve intercepts M and S before it gets to Bob, and then passes M’ and S’ on to Bob. We do not know what Eve may have done while intercepting the message. Bob, taking the message and signature that he received, uses Alice’s public key (which he already had beforehand). Bob is able to verify that S’ is the valid signature for M’. Which of the following should be true? (Select all that apply)

With IPv6, NAT (network address translation) is no longer necessary.

The initialization vector (IV) of block cipher modes (such as AES-CBC) must be kept secret, along with the block cipher secret key.

A secure cryptographic hash function is collision-free.

Use the following table of exchange rates to solve the problem. Round your answer when appropriate. How many Mexican pesos can you buy for $120?

Your laptop is trying to connect to a printer on the local WiFi network, and it knows the printer’s local IP address. To do so, your laptop uses DHCP to determine the printer’s MAC address from its IP address.
