What is the definition of symmetric encryption?

• A basic type of encryption that is not very robust

• Encryption that uses the same key for encrypting and decrypting

• Encryption that uses the same algorithm for encrypting and decrypting

• An advanced form of encryption that makes use of multiple keys.

Match the following

• Used for decrypting cipher text

• Private Key

• Used for encrypting plain text

• Digest

• Produced by putting the plain text through a hash algorithm

• Public Key

The type of encryption that uses two keys is called __________ key cryptography

A digital certificate is used to verify ​ (a)   of a device or service. They are distributed by a ​ (b)   . The ​ (c)   protocol makes use of these certificates during the ​ (d)   process where both sides verify each other.

• the identity
• certificate authority
• SSL/TLS
• handshake
• introduction
• the IP address
• certificate agency
• TCP/IP

Reorder the following statements to describe the basic asymmetric encryption process

• The recipient sends the public key to the sender

• The recipient decrypts the cipher text with their private key

• The sender contacts the recipient to begin an an encrypted communication session

• The sender encrypts the plain text into cipher text, and sends it to the recipient

• The recipient generates the private and public keys

Which technique is used to verify that a message was not modified during transmission?

• Digital Certificate

• Asymmetric Encryption

• Digital Signature

• Digests
