WGU D334 AIO POWERPOINT CHAPTER 1-6
STUDY GUIDE QUESTIONS WITH COMPLETE
SOLUTIONS
changing plaintext into cypher text --CORRECT--encryption
changing cypher text into plain text --CORRECT--decryption
encryption should be applied to --CORRECT--rest
transit
you can use to encrypt individual files --CORRECT--aescrypt
you can use or to encrypt full disk --CORRECT--
bitlocker filevault
is where a single mapping from our alphabet to a cipher is created
--CORRECT--mono alphabetic code / substitution
refers to the mapping of our alphabetto a number of cipher alphabets
--CORRECT--polyalphabetic
is considered to be unbreakable since it only uses its cipher code once
--CORRECT--one time pad
, this method repeats the random numbers after a given time(periodic)
they are fast and are also deterministic and are useful in producing a
repeatable set of random numbers --CORRECT--pseudo random number
generators (PRNGs)
this method generates a true random number and uses some form of random
process
this approach is generally slow, non deterministic and not periodic --
CORRECT--true random number generator (TRNG)
A technique that is based on how frequently certain letters appear in English
versus others. --CORRECT--frequency analysis
is the degree of uncertainty of the encryption process --CORRECT--Entropy
which encryption is faster? hardware or software? --CORRECT--hardware
is a tamper resistant evident and intrusion resistant physical device
that safeguards and manages cryptographic key and provides cryptographic
processing --CORRECT--Hardware Security Module (HSM)
A is a dedicated processor that handles hardware-level encryption;
allows the use of full disk encryption on a hard drive in a manner that
minimizes the impact on system performance. --CORRECT--trusted
platform module (TPM)
