AP CSP Encryption and Decryption Quiz

What is symmetric encryption?

• Encryption where the key is only used for decryption of the data.

• Encryption where the key is only used for encryption of the data.

• Encryption where the same key is used for both encryption and decryption of the data.

• Encryption where different keys are used for encryption and decryption of the data.

What is asymmetric encryption?

• A cryptographic method that uses two different keys, a public key and a private key, to encrypt and decrypt data.

• A method of encryption that only uses a private key to encrypt and decrypt data.

• A cryptographic method that uses the same key to encrypt and decrypt data.

• A method of encryption that does not use any keys.

What is the Caesar cipher?

• A substitution cipher

• A public key cipher

• A symmetric cipher

• A transposition cipher

Which encryption method uses a public and private key pair?

• Steganography

• Asymmetric encryption

• Symmetric encryption

• Hashing

In the Caesar cipher, what is the key used for encryption and decryption?

• The number of letters in the message

• A fixed number of positions to shift the letters in the alphabet.

• The ASCII values of the letters

• A random sequence of numbers

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

• Faster and more efficient encryption and decryption

• Enables encryption of larger amounts of data

• Allows for easier key management

• More secure encryption and decryption
