coRBAC is a specifically optimized RBAC system for cloud computing environment. It inherits the existing RBAC's role model and dRBAC's domain model, optimizes and improves the access control system for services which are hosted on the cloud computing platform. coRBAC greatly improves the certification process and user experience by reducing the unnecessary process of establishing secure connection...
Single Sign-On is one of the more popular enterprise business integrated solution currently. For the complex self-domains across different application requirements, the article researches the traditional single-point sign-on system, and presents a combined access control model. The main form of the model is implemented on Web-service. It extends RBAC access control model, proposes R-R role mapping...
For the key issue of quality and safety certification of pollution-free agricultural product, this paper mainly researches on the integration work process of pollution-free agricultural product area identification and product certification. It adopts the central distributed topology structure, constructs workflow domains of central node and distributed nodes. Applying the workflow and web services...
Many enterprises, organizations, governments and militaries are all facing a problem: how to protect their confidential documents, especially how to prevent them from being unauthorized copied or redistributed is a serious trouble as lacking of mechanism to forbid this action at present. In this paper we propose a Secure Confidential Document Model (SCDM). The document under the proposed model is...
Security support platform is built on public key infrastructure (PKI) and used to solve authentication, access control, information protection and other issues in network environment. This paper analyzes the security risk existed in network communication, gives the authentication design. It also designs an authentication protocol combining with modern cryptographic algorithms and PKI/CA certificate...
The national grid service (NGS) provides access to compute and data resources for UK academics. Currently users are required to have an X.509 certificate from the UK e-science certification authority (CA) or one of its international peers to access the NGS. The CA must satisfy the requirements for internationally agreed assurance levels and some users find the processes of obtaining and managing certificates...
The paper discussed the emerging technologies that can help address the challenges of trust in cloud computing. Cloud computing provides many opportunities for enterprises by offering a range of computing services. In today's competitive environment, the service dynamism, elasticity, and choices offered by this highly scalable technology are too attractive for enterprises to ignore. These opportunities,...
An access control model based on credibility is proposed. The Community Authorization Service (CAS) is an authentication technology which allows service providers to delegate some policy authority to the virtual organization. While in open distributed systems, provider join or leave the domain frequently, so access-control policy in the server changes quickly. To reduce the server load, threshold...
