Vigenère cipher
Choose an answer
________ is a polyalphabetic cipher that employs an improved code over the scrambled alphabet
1
approach, where a different mapping, based on a keyword, is used for each character of the cipher.
Which type of random number generator would be the best choice if you were looking for fast
2
speed?
In _________ encryption, two electronic keys are used, one is used to encrypt the plaintext, and the
3
other is used to decrypt it back to plaintext.
Which simple cipher method attempts to bolster complexity by adding additional alphabets to be
4
used for the substitution rounds and can change its mapping depending on a variable keyword?
Don't know?

plaintext letters by writing a message in
sequence across a number of rails.

mapped to what type of values? Select all Binary
that apply. Decimal
_____ is the largest positive integer that
divides into two numbers without a GCD
remainder.
If I roll a single standard die, what is the 0.167
probability that I roll a "3"?
If you are sending an encrypted message to
a colleague using secret-key (symmetric) (1) your secret key, (2) your secret key
cryptography, of the choices below, (1)
which key would you use to encrypt the
message, and (2) which key would your
colleague use to decrypt the message?
Which simple cipher method entails creation mono-alphabetic
of a single mapping from a given alphabet
to a cipher alphabet?
The Pigpen cipher uses a polyalphabet
substitution method. False
In _________ encryption, two electronic keys
are used, one is used to encrypt the asymmetric-key
plaintext, and the other is used to decrypt it
back to plaintext.
Which type of random number generator
would be the best choice if you were True random number generator (TRNG)
interested in avoiding repeating to reduce
chances of a value being guessed?
When setting up the table for use with the
Playfair cipher, you should ensure no letters J
are repeated and also be sure to omit which
letter from the matrix?
