基于WPS和WS-Security规范,结合Axis Rampart模块,本文提出了针对WPS的具有安全机制的服务架构,构造了符合WPS接口规范的包含安全信息和GIS空间数据的SOAP消息,并通过测试验证了该安全服务架构已经达到身份认证、消息完整性和机密性的要求。该安全机制的服务架构符合OGC规范,具有良好的可扩展性、可升级性、可移植性,能够对采用OGC规范的空间信息处理的安全提供保障,为WPS应用的普及奠定基础。 Based on the WPS and WS-Security specifications and the Axis Rampart module, this paper proposes a service architecture with security mechanism for WPS and constructs a SOAP message that contains security information and GIS spatial data in compliance with the WPS interface specification. The test proves that this Security services architecture has reached the identity authentication, message integrity and confidentiality requirements. The service mechanism of this security mechanism conforms to the OGC standard and has good expansibility, scalability and portability. It can guarantee the security of spatial information processing adopting the OGC standard and lay a foundation for popularizing WPS applications.
