摘要：病历是病人病情、诊断、和处理方法的记录，是医护人员进行医疗活动的信息传递媒介和执行依据，是临床教学和科研的主要信息源。随着医院信息化的发展，病历逐步从纸张病历过渡到电子病历。电子病历具有超越纸张病历的很多优点，但也存在一些巫待解决的问题。电子病历的安全性保护就是这样一个突出并且重要的问题。
病历内容的机密性、完整性和不可否认性是病历安全的基本要求。电子病历的安全性有赖于法律、管理和技术三个方面。数字签名技术为电子病历的安全提供了技术支持。本论文于XML的电子病历系统，探讨了数字签名技术及其在此系统中的应用和实现。

Abstract: The records are kept by the patients condition, diagnosis, and treatment records, medical staff carried out medical activities and the implementation of information transmission media, the basis of clinical teaching and scientific research is a major source of information. With the development of hospital information, medical history, the gradual transition from paper records to electronic medical records. The paper medical records with electronic medical records than a lot of advantages, but there are some witch to be resolved. Protect the security of electronic medical records is such a prominent and important issue.
Records the contents of the confidentiality, integrity and non-repudiation is a basic requirement for medical records security. The security of electronic medical records depends on legal, regulatory and technical three areas. Digital signature technology for the security of electronic medical records provided technical support. In this paper, the electronic medical records system in XML to explore the digital signature technology and its application in this system and realized.
