OOA/D of SET Protocol Using UML

• Problem Specification
• This is a Payment System using SET Protocol
  to manage the Shopping Mall on Web Site by
  Merchant. There are 4 entities, Customer,
  Merchant, Payment Gateway, and Certificate
  Authority on SET. Cardholder needs to install the
  electronic wallet software, and then write the
  registration form which will be sent to
  Certificate Authority(CA) to get a Certificate
  for purchasing the goods.
• After CA is requested the Certificate from
  the Cardholder, it checks the validity of credit
  card number at Cardholders bank, and then
  confirm the Cardholders identity. If all the
  checks is good, CA send the certificate to the
  Cardholder.
