The architecture of the solution includes the ability for them to leverage both XML Digital Signature and XML Encryption to address authentication, data integrity, and dataconfidentiality.
解决方案的体系结构包括使用 XML 数字签名（XML Digital Signature）和 XML 加密（XML Encryption）来满足验证、数据完整性和数据机密性的需求。

In this way, dataconfidentiality can be ensured on the topic, even if some logic must be implemented to encrypt messages on the central reservation system.
通过这样，可以确保主题上的数据保密性，不过必须在中央预约系统上实现某种逻辑来加密消息。

The encryption guarantees the dataconfidentiality on the topic, because only the service provider owning the right private key can perform decryption correctly and, thus, understand the data.
