A Novel Sharing M-Coupons with Lightweight Computations via Cloud Computing

Abstract

Coupons are useful and widely used in the market place to attract new customers and keep loyal customers. As more and more wireless devices are connected to the Internet, many have computed that mobile commerce will blossom soon, just like e-commerce booming in recent years. In this paper, we proposed a secure sharing m-coupon scheme that a user can use the mobile device to share the sharable m-coupons to his/her friend through the cloud. In the proposed scheme, a customer does not need to download the m-coupon from cloud. If customer wants to redeem the m-coupon, he just needs to send a redemption request message to the cloud, and the cloud will help the customer to transfer the m-coupon to the retiler. So that the customers do not worry about problem of storing and losing, it is convenient for customers. Our implementation incorporates only lightweight computations, message authentication code, and simple hash chains for security.
