Encryption Quiz

What is the main purpose of encryption?

• To store data securely

• To speed up data transmission

• To prevent data from being intercepted

• To make data unreadable to unauthorized users

What is the original data before encryption called?

• Encoded data

• Encrypted text

• Plaintext

• Ciphertext

In symmetric encryption, what is true about the encryption key?

• It is different for encryption and decryption

• It is the same for both encryption and decryption

• It is not needed for decryption

• It can be shared publicly

What is the term for the data after it has been encrypted?

• Secure data

• Encoded text

• Plaintext

• Ciphertext

What is a major drawback of symmetric encryption?

• It is too slow for modern computers

• It requires a single key for both parties

• It cannot encrypt sensitive data

• It is easily understood by eavesdroppers

What are the two keys used in asymmetric encryption?

• Master key and slave key

• Symmetric key and asymmetric key

• Encryption key and decryption key

• Public key and private key

What does the public key in asymmetric encryption do?

• It is only for internal use

• It is kept secret by the user

• It is used to encrypt messages

• It is used to decrypt messages

How does Tom send a confidential document to Jane?

• By using a shared secret key

• By using his private key

• By using Jane's public key

• By sending it in plaintext

What is the main advantage of asymmetric encryption over symmetric encryption?

• It is easier to implement

• It provides better security

• It uses a single key

• It is faster

What is a potential future challenge for encryption mentioned in the text?

• The decrease in data sensitivity
