Grid Computing

Increased safety is provided; security technologies and methods in distributed IT environments of whenever data leave the (protected) area of the company’s own IT or external applications and systems are used, be it infrastructures and platforms for data exchange between companies in the use of software-as-a-service offerings, by cloud or grid infrastructures. On the way from the user and client to the data processor or IT infrastructure provider, a backup of the transmitted data is necessary. This should both parties mutually authenticate and authorize access through the other side according to defined rules. In a distributed infrastructure with more than one party wants to identify themselves also not every time again, you use a single-sign-on. This requires the disclosure of information to the authentication and authorization of the user about the chain of participating providers. Here at the so-called trust challenges delegation, in particular as regards the balance between security and Is usability of the technologies used. Several vendors are increasingly involved in cloud scenarios, unless subcontractor chains or the aggregation of various services to a new higher – value – offer. In the project”use of short-lived certificates in portal-based grids the Fraunhofer IAO together with partners of the Alfred-Wegener-Institut, the DAASI international and Gottingen University medical methods and tools to simplify the use of security solutions developed, which should help to eliminate the entry barriers on the way to the grid. In the Project Services@MediGRID the new solutions for the grid-portal of the MediGRID infrastructure then in practice implemented. In the context of the Institute’s own cloud laboratory experts of the Fraunhofer IAO are currently working on the development and transfer of knowledge on cloud scenarios.
