Types of Encryption

What type of key is used in Symmetric Encryption?

• One key for both encryption and decryption

• Two different keys

• No key is used

• Only private keys are used

Which of the following is an example of Asymmetric Encryption?

• AES

• DES

• RSA

• Blowfish

Why is Asymmetric Encryption considered more secure?

• It uses larger key sizes

• It uses a pair of keys - public and private

• It does not require a key for encryption

• It works without mathematical algorithms

What is the main disadvantage of Symmetric Encryption?

• Slow speed of encryption

• Requires separate keys for encryption and decryption

• Difficulty in securely sharing the key

• Not suitable for large datasets

Which encryption method is more suitable for encrypting large amounts of data quickly?

• Symmetric Encryption

• Asymmetric Encryption

• Hashing

• None of the above

How can a symmetric key be securely shared between two parties?

• Encrypt it with Asymmetric Encryption

• Share it in plaintext over a secure channel

• Use a shorter key for sharing

• Key sharing is unnecessary in Symmetric Encryption

Which scenario highlights a key difference between Symmetric and Asymmetric Encryption?

• Symmetric Encryption is used to encrypt emails, while Asymmetric encrypts files.

• Asymmetric Encryption requires two keys, while Symmetric uses one.

• Symmetric Encryption is slower than Asymmetric Encryption.

• Asymmetric Encryption does not require a key for decryption.

Which encryption type is more prone to man-in-the-middle attacks during key exchange?

• Symmetric Encryption

• Asymmetric Encryption

• Both are equally prone

• Neither are prone

A financial institution wants to secure online transactions. Which encryption type should it prioritize and why?

• Symmetric Encryption, because it is faster

• Asymmetric Encryption, because it ensures secure key exchange

• Symmetric Encryption, because it uses smaller keys

• Hashing, because it does not use keys

True or False: Symmetric Encryption is less secure than Asymmetric Encryption due to key-sharing challenges.

• True

• False
