A Security Approach for Credential-Management in Distributed Heterogeneous Systems

摘要

In distributed computing environments information is stored in different locations using different technical systems. Challenging is to allow easy access to heterogeneous resources without an uniform user management and to combine data from different resources for further processing. To delegate the user requests the according login data for different resources have to be present in a central location. The management of these highly sensible data comprises miscellaneous security aspects, e.g. to develop methods to store login data in a secure way. In this paper a security concept to deal with sensitive login data in a central component is presented. This includes a collaboration with the operators of the distributed resources and is discussed in the context of the knowledge infrastructure WisNetGrid.
