Asymmetric encryption is slower and less efficient than symmetric encryption, but it provides better security and enables digital signatures and key exchange protocols.

In summary, symmetric encryption uses the same key for encryption and decryption, while asymmetric encryption uses a pair of keys for encryption and decryption.

Question 13. What is a digital signature and how does it provide integrity and authenticity?

A digital signature is a cryptographic technique used to verify the authenticity and integrity of digital documents or messages. It involves the use of a private key to generate a unique digital signature that can be attached to the document or message.

To provide integrity, the digital signature uses a hash function to create a fixed-size digest of the document or message. This digest is then encrypted using the private key of the sender, resulting in the digital signature. Any alteration or modification of the document or message will result in a different digest, making the signature invalid.

To provide authenticity, the digital signature can be verified using the sender's public key. The recipient can decrypt the digital signature using the public key and compare it with a newly computed digest of the received document or message. If both digests match, it ensures that the document or message has not been tampered with and was indeed sent by the claimed sender.

In summary, a digital signature provides integrity by ensuring the document or message has not been altered, and authenticity by verifying the identity of the sender.

Question 14. What is a secure hash function and why is it important in software security?
