Instead of the traditional credit card payment system, we propose a new electronic payment system for use in a mobile environment. The idea behind this payment service is that a user (customer) applies a message delivery service to obtain a varied authentication token from a servicing bank through his cell phone. The token is used to ensure the validity of the transaction and the legality of the user. On the other hand, because only the user knows the authentication token, he/her cannot later deny that he/her made the transaction. Therefore, in addition to authentication, the property of non-repudiation can also be achieved by using our proposed scheme. Most importantly, our scheme does not require any credit card or tamper-resistant device (i.e. smart card) to store critical information. Consequently, the electronic payment system enhances the security of the traditional credit card payment system. The proposed scheme eliminates the risks of losing a card and duplicating the content of a user's card by a dishonest merchant.
