摘　　要：提出了一种基于Cloudlet的安全信任模型,以通过利用云计算基础架构来保证Web服务之间的安全通信。该模型解决了Web服务使用者通过由政府机构控制的受信任第三方与电子政务Web服务进行通信时出现的问题。Cloudlet通过Web服务使用者的反馈来度量Web服务提供者的可信度和已发布策略的一致性。与数据链系统密钥管理模型(TPM)相比,提出的安全信任模型加密时间短且吞吐量较好,具有较好的实际应用价值。This paper proposes a security trust model based on cloudlet to ensure secure communication between Web services by using cloud computing infrastructure.This model solves the difficulties caused by communicate between trusted third party controlled by government agencies and Web service when used by Web users.The credibility of Web service providers and their consistency of Web service is measured by the feedback from the Web users by Cloudlet.Compared with the practical key management model(TPM),the TPM model has better security throughput and better application value.
