Single Sign-On in Service-Oriented Computing

چکیده
Support for Single Sign-On (SSO) is a frequently voiced requirement for Service-Oriented Computing. We discuss SSO strategies and approaches, their requirements and constraints. The two most prominent approaches in this field are presented, i.e. Microsoft Passport and Liberty Alliance. Because implementations of Liberty were not widely available and in order to understand the conceptual implications and practical requirements of SSO we have built our own SSO solution. Its modular and flexible design is compatible with the Liberty specifications. The prototype reveals valuable insights into SSO design and operations.

Cloud Computing is a concept which serves the computing resources, like Hardware Infrastructure, platform, software application as a Service. Client just need to get connect with the service to use all the computing resources. Cloud users no need to deploy the resources at their site because resources are available at the provider’s side and they provide it and charged on usage basis. This pape...
متن کاملAn Autonomic Service Oriented Architecture in Computational Engineering Framework
Service Oriented Architecture (SOA) technology enables composition of large and complex computational units out of the available atomic services. Implementation of SOA brings about challenges which include service discovery, service interaction, service composition, robustness, quality of service, security, etc. These challenges are mainly due to the dynamic nature of SOA. SOAmay often need to ...

متن کاملAn Efficient, Robust, and Secure SSO Architecture for Cloud Computing Implemented in a Service Oriented Architecture
Implementing Single Sign-On (SSO) in a Cloud space for a spectrum of services and applications is an interesting research avenue for scientific communities in the field of secure identity and access management for Cloud Computing. Using an SSO implementation, in the backend, users can navigate any or all of the supported applications or resources without the need to repeatedly provide credentia...
متن کاملSecurity for Distributed Web-Services via Aspect-Oriented Programming
Identity Management is becoming more and more important in business systems as they are opened for third parties including trading partners, consumers and suppliers. This paper presents an approach securing a system without any knowledge of the system source code. The security module adds to the existing system authentication and authorisation based on aspect oriented programming and the libert...
