representation of encrypted data. | B. They introduce randomness into the encryption process. | C.
They ensure the security and strength of encryption. | D. They facilitate the transmission of encrypted
messages.
ANSWER
C. They ensure the security and strength of encryption.
Question 2.
RSA classification
ANSWER
Asymmetric/public-key cryptography.
Question 3.
Why did NIST select Ascon?
ANSWER
To provide cryptographic protection suitable for IoT and other small devices with limited
resources.
Question 4.
Cryptography and employee privacy
ANSWER
Organizations may face ethical issues when security monitoring or cryptographic controls
conflict with employee privacy interests.
,Question 5.
Digital signature
ANSWER
A cryptographic mechanism used to verify authenticity and integrity and support
nonrepudiation.
Question 6.
Which encryption method is associated with symmetric encryption? | A. Advanced Encryption
Standard (AES) | B. Elliptic-curve cryptography (ECC) | C. Rivest-Shamir-Adleman (RSA) | D. Diffie-
Hellman
ANSWER
A. Advanced Encryption Standard (AES)
Question 7.
Proof-of-work
ANSWER
A consensus mechanism in which participants perform computational work to satisfy a
cryptographic requirement.
Question 8.
Cryptography and organizational policy
ANSWER
Cryptographic controls should align with organizational security objectives and policies to
maximize the effectiveness of data protection.
Question 9.
Primary cryptographic purpose of hashing
ANSWER
To support message and data integrity by making unauthorized modification detectable.
, Question 10.
GDPR and encryption
ANSWER
GDPR recognizes encryption as a measure that can help safeguard personal data.
Question 11.
Hash function
ANSWER
A one-way mathematical function that converts input data into a fixed-size hash or digest.
Question 12.
Digital signature provides
ANSWER
Authenticity, integrity, and support for nonrepudiation.
Question 13.
IV
ANSWER
Initialization Vector; a value used to introduce variation into cryptographic operations such as
CBC.
Question 14.
Nonrepudiation
ANSWER
Assurance that prevents
a sender or signer from credibly denying having performed an action such as sending or
signing a message.
