Encryption Quiz

What is encryption?

• A process used to secure data during transmission

• A process used to convert data into a coded form

• A process used to easily understand data by unauthorized users

• A process used to minimize the risk of data interception

What is the purpose of encryption when transmitting data?

• To easily understand data by unauthorized users

• To minimize the risk of data interception

• To convert data into a coded form

• To secure data during transmission

What is symmetric encryption?

• An encryption method that uses a single key for both encryption and decryption

• An encryption method that uses different keys for encryption and decryption

• An encryption method that uses a public key for encryption and a private key for decryption

• An encryption method that uses a private key for encryption and a public key for decryption

What is asymmetric encryption?

• An encryption method that uses a single key for both encryption and decryption

• An encryption method that uses different keys for encryption and decryption

• An encryption method that uses a public key for encryption and a private key for decryption

• An encryption method that uses a private key for encryption and a public key for decryption

What is the purpose of the public key in asymmetric encryption?

• To encrypt data before sending it to the receiving party

• To decrypt data that was encrypted using the private key

• To ensure the integrity and origin of the data

• To verify that a message comes from a particular sender

What is the purpose of the private key in asymmetric encryption?

• To encrypt data before sending it to the receiving party

• To decrypt data that was encrypted using the public key

• To ensure the integrity and origin of the data

• To verify that a message comes from a particular sender

What is the benefit of asymmetric encryption?

• Eliminates the need for exchanging keys

• Increases security by not transmitting or revealing private keys

• Enables the use of digital signatures

• All of the above

What is the disadvantage of asymmetric encryption?

• It's a slow process compared to symmetric cryptography

• If an individual loses his private key, he can't decrypt the messages he receives

• Public keys can't be authenticated

• A malicious actor can read messages if they identify a person's private key

What is an example of using asymmetric encryption?

• Digital signatures

• Encrypted emails

• Whatsapp

• Cryptocurrencies

What is the purpose of SSL (secure socket layer)?

• To validate a message using a mathematical technique

• To ensure emails can only be read by sender/receiver

• To establish secure links between websites and browsers

• To make sure only legitimate owners can spend the funds in cryptocurrencies
