Cryptography

Question 1

is the science of securing communication
and data through mathematical techniques.

Answer 1

Cryptography

Question 2

The process of converting plain text into an unintelligible
format, known as ciphertext, to prevent unauthorized access.

Answer 2

Encryption

Question 3

Uses a single key for both encryption and
decryption.

Answer 3

Symmetric Encryption

Question 4

Uses a pair of keys – a public key for
encryption and a private key for decryption.

Answer 4

Asymmetric Encryption

Question 5

These are used to verify the authenticity and integrity
of a message.

Answer 5

Digital Signatures

Question 6

Hash functions are used to ensure data integrity by transforming
input data into a fixed-size string of characters, which appears random
but is unique to the input.

Answer 6

Hashing

Question 7

A framework for managing encryption
keys, digital certificates, and secure communication using asymmetric
encryption.

Answer 7

Public Key Infrastructure (PKI)

Question 8

can be used to analyze patterns in
encrypted data.

Answer 8

Statistical methods

Question 9

is a cutting-edge area that uses the principles of
quantum mechanics to develop more secure encryption methods.

Answer 9

Quantum Cryptography

Question 10

At the core of blockchain technology is cryptography. Cryptographic
techniques ensure that the blocks in the blockchain cannot be tampered with,
providing a decentralized and secure way to verify transactions.

Answer 10

Blockchain Technology

Question 11

Cryptography ensures that communication between two parties can occur without
third parties eavesdropping or tampering with the messages.

Answer 11

Secure Communication
