In this paper, we propose a new ef.cient and securemicro-payment scheme, named e-coupons, which can providethe users the facility of delegating their spending capabilityto other users or their own devices like Laptop,PDA, Mobile Phone, and such service access points. Thescheme has the promise of becoming an enabler for variousInternet-based services involving unit-wise payment. Itgives flexibility to the users to manage their spending capabilityacross various access points for a particular servicewithout obtaining an authorization for each and every accesspoint from a facilitating bank. This flexibility which isnot present in the existing micro-payment schemes is essentialfor accessing ubiquitous e-services and other Internet-basedapplications. The facility of delegation introduces aslight overhead in respect of the proof or verification of thedelegated authorization and security provided to the payments.The payoff from the facility of delegation takes awaythe burden of the overhead. The paper discusses the designof the protocol and provides a basic analysis of the performanceof the system.
