The construction and effective application of net based educational resources are of great importance for E-Learning.SOA(Service Oriented Architecture)enables the reuse and share of net based educational resources by publishing the resources as web services.However,frequent identity authentication in resources access among different providers takes up overfull system resources and lower the implementation efficiency.We propose a unified access control model(UACM)based on SAML and security access control technology.UACM meets the requirement of effective access to educational resources and reduces the cost of construction.%基于网络的教育资源的构建和有效利用对于E-learning而言,是非常重要的。SOA(面向对象的架构)通过将资源作为网络服务发布,使得基于网络的教育资源的重新使用和分享变为可能。然而,对于由不同提供者提供的资源获取中频繁的身份认证,占用了全部的系统资源并且降低了执行效率。本文提出一个基于SAML和安全访问控制技术的统一获取访问模型(UACM),UACM满足了对于教育资源有效访问的需求,降低了重建的花费。
