Introduction to Cryptography




LATEST FINAL ASSESSMENT

Q&S




©2024/2025

,1. Multiple Choice: What is the primary purpose of using a
cryptographic hash function in cloud computing?
a) Data compression
b) Error detection
c) Ensuring data integrity
d) Data analysis
Correct Answer: c) Ensuring data integrity
Rationale: Cryptographic hash functions are used to maintain
data integrity by creating a unique digital fingerprint of data, which
helps in detecting tampering or alterations.


2. Fill-in-the-Blank: In asymmetric cryptography, the key used to
encrypt data is known as the __________ key.
Correct Answer: public
Rationale: In asymmetric cryptography, the public key is used for
encryption, while the private key is used for decryption.


3. True/False: Symmetric key algorithms require more
computational power than asymmetric key algorithms.
Correct Answer: False

©2024/2025

, Rationale: Symmetric key algorithms are generally faster and
require less computational power than asymmetric key algorithms
because they use the same key for both encryption and decryption.


4. Multiple Response: Which of the following are characteristics of
a secure hash algorithm? (Select all that apply)
a) Fast computation
b) Pre-image resistance
c) Large key sizes
d) Avalanche effect
Correct Answers: b) Pre-image resistance, d) Avalanche effect
Rationale: A secure hash algorithm should be pre-image resistant,
making it computationally infeasible to reverse the hash value to its
original input, and should exhibit the avalanche effect, where a
small change in input results in a significantly different hash.


5. True/False: In cloud computing, encryption at rest is less critical
than encryption in transit.
Correct Answer: False
Rationale: Both encryption at rest and in transit are critical in
cloud computing to protect data from unauthorized access and
breaches.
