云计算环境下的数字图书馆具有支持大量资源共享、具备强大计算能力等特点，但同时也因其支持多用户共享资源而带来了诸如存储数据被还原篡改、信息隐私泄露、通信数据被窃听等等安全问题。其中，以虚拟化技术为关键技术的“基础设施即服务”（IaaS）模式亦如此。鉴于此，论文从服务提供商、租赁用户、服务提供商和租赁用户间供求关系的角度出发，探讨了云图书馆服务架构中IaaS模式的资源共享安全问题，并提出了相应的安全策略。

Digital library under the cloud computing environments has many features,such as resource sharing and powerful com-puting capabilities.However,because of sharing resources for many users, the security problems such as data tempering 、privacy leaking bring to the users.The“Infrastructure as a Service”(IaaS) model, which using the virtualization technology as the key tech-nology, also has the security problems. Becouse of this reason, this paper discusses the security problem of the IaaS model in the cloud library architecture, thinking in terms of The service provider、rental user、relationship betwee n the service provider and rental user. Lastly, this paper presents the corresponding security strategies.
