What is the general goal of the cipher modes? Why is the ECB mode not recommended? Briefly describe how the CBC mode works. Typically, are stream ciphers more robust than block ciphers? What is another name for asymmetric encryption? What are the last names of the researchers that invented asymmetric encryption? (This is actual useful data by the way) What does the security of an asymmetric encryption system relies on? In asymmetric encryption, do the sender and receiver need to exchange any information before starting a secure communication exchange? What do we mean when we say that in asymmetric encryption one key undoes the action of the other? What are the names of the two keys in an asymmetric encryption system? What is the name of the structure used to distribute asymmetric keys? Briefly describe the information a digital certificate contains. Why are asymmetric encryption methods not typically suitable for bulk encryption? What is one of the more common math methods public key systems rely on? What are trapdoor functions? Computer can easily multiply numbers, but what can't they do easily? What is a digital signature? Name four popular asymmetric key protocols. What does the Diffie-Hellman algorithm enable? Which algorithm is implemented in TLS, SSH and IPSec? Name a use of the Diffie Hellman algorithm. Name a use of the RSA algorithm. Name a use of the ElGamal algorithm. What is post-quantum computer and why is it needed? Which of the five components that make up security is not addressed by encryption? Which component of security enables the sender and recipient to know if the message was not changed in transit? What does the security component of non-repudiation guarantee? What does a digital signature demonstrate? Does a digital signature by itself protect the contents of a message from interception? What does PGP stand for? What kind of encryption does PGP use? What encryption algorithm does Windows' BitLocker use? Where is the key stored?
