CS 1.3.1 Encryption

What is the primary purpose of encryption?

• To increase data size

• To keep data secure during transmission

• To make data readable

• To reduce data transmission time

In symmetric encryption, what is shared between the sender and receiver?

• A public key

• A private key

• A password

• A digital certificate

What is the process called when the private key is distributed in symmetric encryption?

• Key generation

• Key exchange

• Key encryption

• Key decryption

What is a major risk associated with symmetric encryption?

• The public key can be intercepted

• The private key can be intercepted

• The data can be compressed

• The data can be duplicated

How does asymmetric encryption address the issue of key interception?

• By using a single key

• By using two keys: one public and one private

• By using a password

• By using a digital signature

Which key in asymmetric encryption can be freely shared?

• The private key

• The public key

• The symmetric key

• The digital key

What must be kept secret in asymmetric encryption?

• The public key

• The private key

• The encryption algorithm

• The data size

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

• Asymmetric encryption

• Symmetric encryption

• Public encryption

• Digital encryption

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

• Faster encryption process

• No need to share a private key

• Smaller data size

• Easier to implement

Which of the following is NOT a characteristic of symmetric encryption?

• Uses a single key

• Faster than asymmetric encryption

• Requires a key exchange

• Uses two keys: public and private
