A painter comes up with a new business idea: He wants to offer custom paint- ings from photos. Both the photos and paintings will be transmitted in digital form via the Internet. One concern that he has is discretion towards his customers, since potentially embarrassing photos, e.g., nude photos, might be sent to him. Hence, the photo data should not be accessible for third parties during transmission. The painter needs multiple weeks for the creation of a painting, and hence he wants to assure that he cannot be fooled by someone who sends in a photo assuming a false name. He also wants to be assured that the painting will definitely be accepted by the customer and that she cannot deny the order. 1. Choose the necessary security services for the transmission of the digitalized photos from the customers to the painter. 2. Which cryptographic elements (e.g., symmetric encryption) can be utilized to achieve the security services? Assume that several megabytes of data have to be transmitted for every photo.
