Title: A cryptographic method
Inventor: CHEN JAY CHIEH
IPC: G07F7/08
Filed: 1999-05-05
Abstract: An electronic transaction method, which facilitates secure electronic transactions among multiple parties including cardholders (20), merchants (70), and service providers (SP) (60). The method involves electronic cards, commonly known as smart cards, and their equivalent computer software package. The card mimics a real wallet and contains commonly seen financial or non-financial instruments such as a credit card, checkbook, or driver's license. A transaction is protected by a hybrid key cryptographic system and is normally carried out on a public network such as the Internet. Digital signatures and random numbers are used to ensure integrity and authenticity. A first phase of the method involves a key exchange response including the use of message at least partly encrypted using a public key of the service provider which is stored on the ic card. This is passed, together with an encrypted message by the merchant, as a composite message, to the service provider. A composite response from the service provider is returned, via the merchant who strips off his part, to the cardholder and which message provides a session key with which the financial transaction can be completed.
