Betty needs to send over a contract for a new house for George to sign. George needs to ensure that the contract did, indeed, come from Betty and hoth parties need to ensure that the amount that Betty stated in the contract did not change. They both want to keep the details of the transaction secret. Answer questions1-4 as they relate to asymmetric encryption: 1. Which key, and whose key, will be used by the sender to provide authentication of origin, so George knows it came from Betty? Which key, and whose key, will be used to decrypt the message digest? How does this process provide for non repudiation? (2 points each question total 6 points) 2. Identify an algorithm that could be used to create the message digest and explain how a hashing algorithm provides for message integrity. (3 points each part - total 6 points) 3. Discuss how asymmetric cryptography would be used to provide confidentiality in this example. (6 points) 4. Identify a symmetric algorithm and provide at least one advantage and disadvantage to symmetric encryption (2 points for each correct answer for a total of 6 points). 5. Discuss an instance where symmetric and asymmetric encryption are used together and why. (6 points)
