【 摘 要 】

This paper evaluates four micropayment schemes: Millicent, MicroMint, Payword, and Wenbo Mao's simple cash payment technique for the Internet. The paper first describes the differences between macro- and micropayment schemes, the notion of anonymity in electronic commerce, and common features used in payment protocols. It then examines details of the four payment protocols. The paper concludes with a summary of the features of the four payment schemes and compares their computation costs and storage requirements.
