| 摘 要： | 已存在的时间戳机制没有解决服务付费问题，即客户在请求时间戳服务机构给他的文档Hash值加盖时间戳时，应该如何向时间戳服务机构支付费用。介绍了已经存在的时间戳机制，基于盲数字签名，提出了一个解决问题的新方案，该方案引入了一个售票实体，解决了服务付费问题，并且基于RSA数字签名，构造了一个完整的时间戳系统。

| Abstract: | Billing service question is not solved in the existing time-stamp schemes. In other words, how the time-stamping Service will bill the service to its customers when they ask it for a Digital time-stamping. This article described the existing time-stamping schemes, based on blind signature,a new scheme solving the problem was presented. In the new scheme an issuing entity of tickets is introduced to solve billing service question. Based on RSA signature, an integrated time-stamping system was constructed in this article. |
