Time-stamp is an critical part for electronic document

 

 Hi,

 

This is my first document in the CSDN.  Hope you will like this topic!

 

Time-stamp is an critical part for any electronic document, especially for some special documents, like electronic medical record. In simple words, if you need to demonstrate when was a document established, you must provide its time-stamp. However, time-stamp technology is not a simple technology. Acquiring reliable time-stamp is always  a hot topic!

• First, the important thing is that choosing a time-stamp protocol which can provide reliable time-stamp for your documents. There are many different time-stamp protocols. For example, the Simple Time-stamp Protocol, the Linear Time-stamp Protocol and so on. Of course, if all of those existed protocols cannot satisfy your project, you can propose neval time-stamp protocol, like that I do!
• Second, to verify the choosing protocol's work is another important work to do.

If you want to know details about TSP, you can see a criterion --- rfc3161 (http://www.ietf.org/rfc/rfc3161.txt )

Please send message to me, if you have any question!

对于电子文档来说，时间戳是一个很关键的部分。尤其是对一些特殊文档，比如电子病历，电子合同等。简单来说，如果你需

要提供文档的创建时间，那你就需要时间戳。但是，时间戳技术并不是一个很简单的技术。首先，你需要了解并选择一个合适

的时间戳协议来提供可信的时间戳。现在，有很多不同的时间戳协议：简单时间戳协议；链接时间戳协议；树形时间戳协议；

分布式时间戳协议等等。当然，如果现存的所有协议都不能满足你项目的要求，你也可以提出新的协议，就像我做的一样。接

着，验证该选择的协议是否工作良好也是很重要的。
