Explanation:
This protocol was created by VISA and MasterCard as a common effort to make the
buying process over the Internet secure through the distribution line of those companies. It is
located in layer 7 of the OSI model, the application layer. SET uses a system of locks and keys
along with certified account IDs for both consumers and merchants. Then, through a unique
process of “encrypting” or scrambling the information exchanged between the shopper and the
online store, SET ensures a payment process that is convenient, private and most of all secure.
