Changing plaintext into ciphertext Elliptic Curve which is often used in

(Should be applied in at rest and in transit) creation of digital signatures:
Single mapping from our alphabet to a
3 16 bit value, up to 65,536 characters 4 cipher alphabet is created.
Many early cryptosystems.

Changing plaintext into ciphertext Encryption
(Should be applied in at rest and in transit)
Changing ciphertext to plaintext Decryption
Encrypt individual files and full disks with Aescrypt
options such as BitLocker and FileVault
Mapping from our alphabet to a number of Polyalphabetic
cipher alphabets.
Added complexity in early cryptosystems.
, Single mapping from our alphabet to a Mono-Alphabetic
cipher alphabet is created.
Many early cryptosystems.
Considered un-breakable since it only uses One-Time Pad
its cipher code once.
Method repeats the random numbers after a Pseudo-Random Number Generators (PRNGs)
given time. (periodic)
They are fast and deterministic.
Useful in producing repeatable set of
random numbers.
Method generates a true random number True Random Number Generators (TRNGs)
and uses some form of random process.
One approach is to monitor the movements
of a mouse pointer on a screen or from the
pauses between keystrokes. Overall, the
method is generally slow, especially if it
involves human interaction, but is non-
deterministic and aperiodic.
Cipher cracking methodology that involves Frequency Analysis
identifying patterns and variations in the
probability of codes.
i.e. a three-letter ciphered text combination
spotted at the beginning of a string too
often could tip us off that those three letters
correlate the letters THE in the English
alphabet.
measures level of unpredictability Entropy
Two common binary to characters encoding ASCII (8bit value, up to 256 characters)
methods UTF-16 (16bit values, up to 65,536 characters)
8 bit value, up to 256 characters ASCII
16 bit value, up to 65,536 characters UTF-16
Tamper-evident and intrusion-resistant Hardware Security Module (HSM)
physical device that safeguards and
manages cryptographic keys and provides
cryptographic processing.
Which encryption is more efficient? Hardware
1 multiple choice option
Dedicated processor that handles Trusted platform module (TPM)
hardware-level encryption; allows the use of
full disk encryption on a hard drive in a
manner that minimizes the impact on system
performance.
Contains the encryption keys.
