Test 3. Encryption in cybersecurity

1. What is encryption in cybersecurity?

Changing the physical properties of data
Converting data from a readable format to an encoded format
Copy data for safekeeping
Random generation of new data

2. How does encryption work in cybersecurity?

Encryption is used to create user IDs
The data is changed to look random and a key is used to decrypt it
All data is automatically converted to encrypted text
Keys are used for data storage only

3. What is asymmetric encryption?

Encryption where only one key is used
Public key encryption
Encryption, where two different keys are used for encryption and decryption
Encryption using quantum principles

4. What algorithms belong to symmetric encryption?

RSA and Public Key Infrastructure (PKI)
DES, Triple DES and AES
RSA and Twofish
Public key infrastructureв (PKI) and AES

5. What principles of quantum mechanics are used in quantum cryptography?

Changes in the physical properties of particles
Complete cloning of quantum systems
Invariability of the quantum system during measurement
Uncertainty and particle measurement
