Abstract: A secure multiple micropayment scheme based on Rivest-Shamir's scheme is proposed. The multiple micropayment scheme overcomes the limitation of Rivest-Shamir's scheme, that is, a PayWord chain can be used for a vendor. The proposed micropayment scheme is not only suitable for long- term and frequent transactions between a user and a vendor, but also suitable for transactions between a user and several vendors. Furthermore the efficiency of the new micropayment scheme is higher than Rivest-Shamir's scheme.
