H466 - 1.3.1 - Understanding Encryption Methods

What is the primary purpose of encryption?

• To increase data size

• To keep data secure during transmission

• To make data readable by everyone

• 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 for both encryption and decryption

• By using two keys: one public and one private

• By using a password instead of a key

• By using a digital certificate

Which key in asymmetric encryption is kept secret?

• The public key

• The private key

• The shared key

• The digital key

Which key in asymmetric encryption can be freely published?

• The public key

• The private key

• The shared key

• The digital key

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

• It uses less computational power

• It eliminates the need for a key exchange

• It is faster

• It uses a single key

Which type of encryption is generally faster for encrypting large amounts of data?

• Asymmetric encryption

• Symmetric encryption

• Hash encryption

• Digital encryption

In asymmetric encryption, what is the role of the public key?

• To decrypt data

• To encrypt data

• To generate a private key

• To store data
