INTRODUCTION TO CRYPTOGRAPHY FINAL PAPER EXAM QUESTIONS ACCURATE
ANSWERS FULL SOLUTION
● What is Cryptographic Strength? Answer: Relies on math, not secrecy
Ciphers that have stood the test of time are public algorithms.
Exclusive Or (XOR) is the "secret sauce" behind modern encryption.
*All of the above.*
Correct! All of these are critical.
● What is the primary difference between Symmetric and Asymmetric
encryption? Answer: The same key is used to both encrypt and decrypt
the message.
Correct! That is what is symmetric about the process.
● Which type of cryptographic attack is characterized by an attack based
upon trial and error where many millions of keys may be attempted in
order to break the encrypted message? Answer: Brute force
