iKP - A Family of Secure Electronic Payment Protocols
This paper proposes a family of protocols { iKP (i = 1; 2; 3) { for secure electronic payments over the Internet. The protocols implement credit card-based transactions between the customer and the merchant while using the existing nancial network for clearing and authorization. The protocols can be extended to apply to other payment models, such as debit cards and electronic checks. They are b...
متن کاملUsing Digital Signatures as Evidence of Authorizationsin Electronic Credit - Card
Credit-card payment protocols such as iKP and SET use digital signatures to authenticate messages and authorize transactions. It is assumed that these digital signatures make the parties' authorizations non-repudiable, i.e., provable to a third-party veriier. In this paper, we deene a set of statements which participants in a payment may want to prove. We then investigate which of these stateme...

This report proposes a micro-payment sc...
