基于安全约束的服务注册与发现模型

Security-constraint based service registration and discovery

随着SOA的广泛部署,服务发现不仅要满足服务功能属性的需求,而且越来越关注服务的非功能属性的需求。如何在众多的服务中去选择满足一定安全要求的服务是一个亟待解决的问题。通过对服务描述进行扩展,加入了安全约束属性,可以丰富灵活地表达服务对安全的需求,在此基础上提出基于安全约束的服务注册与发现模型。本模型是对服务注册中心进行扩展,在注册和发现的过程中能够保证服务注册中心、服务提供者与使用者各方安全需求的充分表达。

With wide deployment of SOA,service discovery not only needs to satisfy the requirements of service function,but also emphasizes on its non-function requirement.How to choose a service that satisfy a certain standard for security is a problem need to be addressed immediately.Expanding the description of service by adding security constraint attribute express the security requirement for service abundantly,pointed out the service registration and discovery model based.The model extended the service registry,ensured the security requirements for service registry,service provider and service requester while registering and discovering service.
