Multi-Vendor PayWord with Payment Approval

چکیده

We extended the PayWord scheme, it supports shopping at multiple vendors without an on-line broker or an on-line secure database. The proposed credit-based system uses one hash chain, hence besides the secret signature key only the seed and a random value should be securely stored. Our scheme is analyzed in applied pi calculus, we prove that it fulfills payment approval, secure payment authorization, secrecy of payment information and unreusability.

Payment Approval for PayWord

In case of micropayment schemes, all costs that appear during functioning should be minimized. This includes cost of disputes and charge backs that result in penalties for the vendor. We extend the PayWord micropayment scheme with payment approval to minimize disputes, charge backs or to avoid attacks that ruin the reputation of the vendor. Payment approval is achieved by employing a MAC functi...

A New Micro-Payment System Using General Payword Chain

In recent years electronic commerce has grown rapidly as Internet and web technologies have progressed. Therefore, a secure and efficient payment system for general-purpose applications is undoubtedly becoming an important issue. Rivest and Shamir have proposed a micro-payment scheme which is user-specific and vendor-specific. However, in their scheme, it is required that the user generates a n...

PayWord and MicroMint: Two Simple Micropayment Schemes

1 Introduction ~Ve present two simple micropayment schemes, "PayWord" and :'MicroMint," for making small purchases over the Internet. We were inspired to work on this problem by DEC's "Millicent" scheme[10]. Surveys of some electronic payment schemes can be found in Hallam-Baker [6], Schneier[16], and Wayner[18]. Our main goal is to minimize the number of public-key operations required per paym...

A parameter-tuned genetic algorithm for vendor managed inventory model for a case single-vendor single-retailer with multi-product and multi-constraint

This paper develops a single-vendor single-retailer supply chain for multi-product. The proposed model is based on Vendor Managed Inventory (VMI) approach and vendor uses the retailer's data for better decision making. Number of orders and available capital are the constraints of the model. In this system, shortages are backordered; therefore, the vendor’s warehouse capacity is another limitati...

An optimization technique for vendor selection with quantity discounts using Genetic Algorithm

Vendor selection decisions are complicated by the fact that various conflicting multi-objective factors must be considered in the decision making process. The problem of vendor selection becomes still more compli-cated with the inclusion of incremental discount pricing schedule. Such hard combinatorial problems when solved using meta heuristics produce near optimal solutions. This paper propose...
