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.
