Answer the following questions:
1. Explain in your own words how public key encryption is not symmetric.
Answer
Public key encryption is not symmetric because it uses a backdoor key, not a common one.
2. Cryptography relies on open standards - a protocol or standard that is publicly available. Why are open standards necessary?
Answer
Open standards are necessary because our access to the internet would be severely limited without open standards. HTTP is an open standard, which allows everyone to access the internet.
