Along with the development of Internet, web services technology is a new branch of web application program, and it has become a hotspot in computer science. However, it has not made great progress in research on web services security. Traditional security solutions cannot satisfy the web services security require of selective protection, end-to-end security and application layer security. web services technology needs a solution integrated in web services framework to realize end-to-end security. Based on cryptography and web services technology and according to W3C, XML encryption specification, XML digital Signature specification and WS-security, which proposed by IBM and Microsoft, a new web services security model based on message layer is put forward in this paper. The message layer is composed of message handlers. It is inserted into the message processing sequence and provides transparent security services for web services. To verify the model, a web services security system is realized on, net platform. The implementation version of the model can provide various security services, and has advantages such as security, scalability, security controllability and end-to-end security in message level. Key words web services - web services security - message layer CLC number TP 393.08 Biography: WANG Cui-ru (1954-), female, Professor, research direction: database and information management system.

HL7(Health Level 7)是医疗信息交换与共享的应用层通信标准。尽管HL7 V2.x(Version 2.0.5)已经在医疗信息交换领域被广泛采用,但由于它们有着自身难以克服的缺陷,实现起来很困难,所以HL7 组织很早就开始制定全新的版本HL7 V3(Version 3.0)。通过广泛采用了现代软件工程技术,HL7 V3 无论在方法论以及编码实现方面,都比HL7 V2.x 优胜,更具有实现价值和社会价值。通过对HL7 V3 原理和实现的深入探讨,本研究进行了以下三个方面的工作。首先,提出了使用web services 技术构建HL7 V3 网关,使得网关的实现不但更容易,而且具有更高的稳定性与健壮性。web services 是一种与平台无关的信息交换协议,是目前企业应用集成(EAI,EnterpriseApplicationIntegration)的主流技术。接着,结合web services security(WSS)提出了一个全面的HL7 V3 网关安全体系架构。WSS 融合了多个业界开放标准,目前已得到了广泛支持。最后,提出了一个完整的网关实现框架,并给出了一个参考实现。该系统模拟了HIS(Hospital Information System)与LIS(LaboratoryInformation System)之间的信息交换。系统的运行测试显示,利用web services构建的HL7 V3 网关,可以很好地实现异构医疗信息系统之间的信息交换。如果将本系统产品化,可满足现阶段的医疗信息交换需要,具有很强的使用价值。
