随着各种服务的大规模应用，其带来的协议适配及安全问题日益凸显，如何建立一种信任服务适配的统一机制，提升服务适配的可用性和安全性，已成为相关行业关注的焦点。在网络信任系统建设中，不同服务间组合共同构成一个完整的网络信任服务体系，形成分布式服务系统的场景越来越多。信任服务之间交互频繁，传统的服务适配机制直接移植到信任服务体系中会极大降低交互效率和扩展性，因此提出一种基于安全代理的信任服务适配方法，主要解决的技术问题为服务适配的可用性、扩展性和安全性。该方案能够满足服务状态自适应变化、提升服务适配的可用性，同时确保交互双方的身份以及保证交互过程中数据安全。

With the large-scale application of various services, protocol adaptation and security issues are becoming increasingly prominent. It has become a focus of attention in related industries to establish an uni?ed mechanism for trust service adaptation, and improve the availability and security of service adaptation. In the construction of industry network trust systems, the combination of di?erent services together forms a complete network trust service system, and there are increasingly more scenarios for forming distributed service systems. The interaction between trust services is frequent, and directly transplanting traditional service adaptation mechanisms to the trust service system will greatly reduce interaction e?ciency and scalability. Therefore, a trust service adaptation method based on secure proxies is proposed, which mainly solves the technical problems of service adaptation usability, scalability, and security. This scheme can meet the adaptive changes in service status, improve the availability of service adaptation, while ensuring the identities of both parties in the interaction and ensuring data security during the interaction process.
