Secure Electronic Transaction (2)
Case Study (SET)
- I browse Web, select Merchant, select Item
- I choose to make a payment with my electronic wallet
- The Merchant server sends an order to my Web browser to open my wallet
- My wallet exchange handshake messages with the server
- confirms that the Merchant is authorized to process payments with my CC
- confirms to the Merchant that I am an authorized card holder
- My wallet constructs the Purchase Order and payment instruction (cryptographically protected)
- Payment instruction is sent to the Merchant gateway server (usually run by the Merchant’s bank)
- My wallet receives purchase-response message. This ends the electronic payment procedure
