What is unique about ROT-13 compared to a typical Caeser Cipher
It is asymmetric
It has two layers of shifting
It has 13 combinations
It is a shift of 13
What is true about Caesar Ciphers?
They are a shift cipher
They are symmetric
They don't have a key
All of these
Can you use only frequency analysis on Vignere Cipher
Yes, if there's 26 shifts
No, if there's a repeating key
Yes, since they shift the same
No, due to encrypting with a key
What happens when you XOR two ciphertexts with the same key
The key gets revealed
The key cancels out
The images encrypt securely
None of these
What is Transposition Cipher?
Encrypting the plaintext then moving the positions
Encrypting plaintext
Moving position of plaintext letters
A type of substitution cipher
Does a Stream Cipher provide a truly secure encryption?
Yes, but with a psuedorandom key
No, since you can reverse XOR each bit
Yes, but only with a random key
No since you can use multiple times
What is padding?
Adding bits to fit block size
Making a longer key
Making the operations longer
All of these
What are the purpose of P and S Boxes?
To compute ciphertext
To make it harder to reverse
To encrypt
All of these
What is the purpose of a Feistal Cipher?
A way to have efficient encryption algorithms
The method to decrypt DES and AES
The padding scheme
A block cipher with 1 round
Does a key schedule enhance security
Yes, since it adds more complexity
No, since it is when a key is used
Yes, since it is a XOR operation
No, since if you work out first key. You can get rest
What is the main strength of AES
It can be used asymmetrically and symmetrically
It is a simple algorithm
It is provably secure
It has psuedorandomness
What is the purpose of CBC
To securely encrypt images
To efficiently do AES encryption
To decrypt images
To produce a code-book for encryption
What is the main feature of asymmetric cryptography
Uses a public and private key
Uses 1 key
Provably secure
It is for decryption
