In E-Commerce, HTTPS is a communication protocol that uses which encryption method?

• A. Public key encryption
• B. Secret key encryption
• C. Private key encryption
• D. Data key encryption

Answer: (A)

HTTPS uses public key encryption to establish a secure connection. In TLS, the server presents its certificate with a public key, and the client uses that key to securely exchange a secret that only the server can decrypt with its private key. From there, both sides derive a symmetric session key used to encrypt the actual data being transferred. So the encryption method used to set up the secure channel is public key (asymmetric) encryption, with symmetric encryption protecting the ongoing data once the session key is established.
