| Cloud computing is applied to the digital information service, which extends the service object, enriches academic resources of service type, improves the service efficiency and saves the overall use of cost. But digital academic resources cloud service features such as openness, sharing, make its complexity of the security issues become more prominent; because the cloud service construction involving the participation of many subjects,has complicated structure and Large scale, and at the same time the digital construction of cloud services is oriented toward sharing academic resources, which is for vast users with cloud services on the basis of the integration of academic information service, information security becomes the key factors of cloud services building and user acceptance. Digital academic resources cloud security guarantee research problem of the selection based on service chain, is based on the need of the national knowledge innovation development of cloud services digital academic resources, and meets the development need of the cloud service in digital academic resources, to ensure the safety of digital academic resources of cloud services.This paper focous on the security problem of digital academic resources information service, do a research from the perspective of service supply chain. During researching, the paper, first of all, through researching the parts of the subject as a supply chain security involved in digital academic resources information service security, analyzes and summarizes the digital academic resources information service safety factors in cloud computing environment. On this basis, the paper, based on the theory of service chain to build digital academic resources cloud service platform security,integrates digital academic content source, digital library and information service providers, regulators, and the third service party through a service chain in the cloud environment and constructs a unified digital academic resources information service cloud platform. In the complex service chain integration of the call, by introducing service level protection on both ends of service chain (SLA) to enhance the level of cloud service platform security, and then cloud services platform to realize digital academic resources for different levels of information demand and the guarantee of differentiated services. the core of Safety chain management in addition to the above platforms, technology elements, also includes the "people". "Person" is both the producer and the user of academic resources. "people" in the cloud environment of scientific research and the exchange process, can produce new academic resources in the cloud, which involves the cloud service user rights, privacy and intellectual property rights. The paper realizes the user identity security controls through introducing a federated identity management architecture into academic resources of cloud services platform; Further the intellectual property protection block chain model is constructed to protect users in the academic exchange and learning resources cloud service under the environment of scientific research innovation in the process of content, promote academic resources by effective guarantee of the right knowledge exchange and innovation of cloud services. Finally the paper taking "CALIS Cloud" services as an example, analyses the academic resource cloud service in the digital security measures in practice, and puts forward the corresponding suggestions.Chapter 1 expounds the theoretical basis of this article. Theory of service chain and supply chain coordination management, total quality management theory, information service security lever protection theory, safety chain theory is introduced into digital cloud security research in academic resources. The chapter respectively expounds Basic connotation of the theory, and explains the guidance and reference significance of the security maintenance, the cloud service platform of cloud service, cloud service user security management for safety control.Chapter 2 analyzes the cloud computing's influence on digital academic resources information service security. By researching supply chain security's closely link, involved in digital academic resources information service security,it analyzes and summarizes the factors of digital academic resources information service security in cloud computing environment.It integrates digital academic content source, digital library,information service providers, regulators and the third party in the cloud environment through a service chain, constructing a unified digital academic resources information service cloud platform. On this basis, based on the theory of service chain, it constructs security model of digital academic resources cloud service platform.Chapter 3 is based on the basic framework of SLA. In complex service chain integration in the call, by introducing service level protection on both ends of service chain (SLA), it enhances the level of cloud service platform security, cloud services platform to realizes digital academic resources for different levels of information demand and the guarantee of differentiated services. Building the service side trust evaluation model based on layer and analysis method, can realize digital academic resources based on trusted cloud service process safety management.Chapter 4 builds the information service security system under the cloud environment of digital scholarly. In terms of the cloud environment academic resources information service chain node number, the complex service variety, in addition to the traditional digital information service, also includes a lot of Internet service provider of open access resources, and because the service nodes in the cloud, is "virtualization", resource information service of the credibility is in doubt. By introducing the analytic hierarchy process (AHP) and gray system theory into digital academic resources information service cloud environment, the chapter put forward the content provider trust evaluation model based on AHP to ensure the high reliability of information service of academic resources effective acquisition, transparent access, publishing and sharing.Chapter 5 focuses on cloud service platform user security controls. the core of safety chain management in addition to the above platforms, technology elements such as, also includes the "people". This chapter firstly analyzes the security problem that user will face in the digital academic resources cloud service environment. The user is not only the user of cloud services, is also the creator of academic resources. digital academic resources cloud services involve the user privacy and intellectual property rights, etc. In order to safeguard the rights and interests of these three kinds of users, by building the identity of the cloud environment management system, privacy, security strategy and the decentralized block chain of intellectual property protection technology, it can protect the safety, rights and interests of users.Chapter 6 takes the CALIS Cloud services digital library as an example to carry out a case study, First researches'the CALIS Cloud'the service application practice and its application in the Cloud of the academic information resources security system and institutional reform, on the basis of which the paper analyses the academic resources in the digital Cloud service platform, service process and user control problems and puts forward some Suggestions to perfect.Chapter 7 makes a comprehensive combing about the full text of research ideas and content, summarizing and refining the research conclusion and view, points out the deficiency of this paper, and discusses the future research direction and way of thinking... |
