Asymmetric Encryption Quiz

What is another name for asymmetric encryption?

• Symmetric-key cryptography

• Hashing

• Public-key cryptography

• Block cipher

A student wants to send an encrypted message to a friend using asymmetric encryption. What should the student use to encrypt the message?

• The friend's private key

• The student's private key

• The friend's public key

• The student's public key

What type of encryption is used by web pages shared using HTTPS?

• Symmetric encryption

• Asymmetric encryption

• Hash encryption

• Block encryption

Why is asymmetric encryption preferred over symmetric encryption for HTTPS?

• It is slower but more secure

• It does not require sharing a password privately

• It uses simpler algorithms

• It does not require any keys

If symmetric encryption were used for HTTPS, what would be required before visiting a website?

• Sharing a public key instantly

• Sending the password privately to the user

• Using only a browser

• No encryption at all

What is the risk if an eavesdropper discovers the public key in asymmetric encryption?

• The data can be easily decrypted

• There is no risk

• The website will crash

• The password will be revealed

The sharing of a public key in asymmetric encryption is considered secure, even if an eavesdropper discovers it, because:

• Because the public key cannot be used to decrypt the data

• Because the public key is changed every second

• Because the public key is encrypted itself

• Because the public key is only used once

Which type of encryption uses the same key for both encryption and decryption?

• Symmetric Encryption

• Asymmetric Encryption

• Public key

• Private key

What is the term for the original readable message or data before it is encrypted?

• Plaintext

• Ciphertext

• Encrypt

• Shared key

What does the process of decryption do?

• Converts encrypted data back into its original form

• Converts plaintext into ciphertext

• Generates a public key

• Shares a key between users
