摘要：JI et a I improved R.Revest's PayWord scheme based on hash chains and proposed a micro-payment scheme which had better security and fairness, but the scheme did not solve the problems of user's malicious overdraft and its executive timeliness. Furthermore its efficiency and security was restricted by the inherent shortcoming of conventional hash chains (CHC). The paper proposes a micro-payment scheme based on Self-Renewal Hash Chains scheme (SRHC). The analysis results show that the proposed scheme not only solves the problems existed in JI's scheme, but also has better features on security, efficiency and fairness. The novel scheme fits scenario of repeated micro-payment such as information commodity between a mobile user and a fixed service provider.
