World Assembly of new industries (the WEIS) is a leading international economic organizations - Asia Pacific CEO Association initiated and organized the world's emerging industries meeting the highest level of international cooperation.
Distributed Systems Prof. Dr.-Ing. Torben Weis Security and Virtual Worlds Two software projects for computer game development and for IT security will be presented by the Distributed Systems group from the University of Duisburg-Essen at CeBIT: Massively Multiuser Online Games (MMOGs) such as World of Warcraft usually use a high- performance central server. Maintaining such a server is highly cost-intensive. Therefore the Distributed Systems group develops in the context of the peers@play project a peer-to-peer- based system for MMOGs which does not need a central high- performance server. Without such a server, a peer-based system has the potential of being highly cost- effective. In peers@play the resources of all participants are used to maintain the entire system. Ideally a peer-based system can scale indefinitely as long as every participant introduces at least as many resources as he is using. However, creating a peer-based system and coordinating the participating computers so that all have the same view of the world, is significantly more difficult. All data and information must be permanently redistributed in the network if a participant leaves the network or new ones join. The researchers working together with Prof. Torben Weis are close to finding a solution: They have developed an early prototype based on a peer-to-peer system, which is presented at their booth on the CeBIT. Cryptography is an essential element in order to protect data, for example during online banking or mobile telephony. The e-learning program CrypTool is used around the world for teaching cryptography. The researchers of the Distributed Systems group participate in the development of the successor. CrypTool 2 enables the user to experiment with cryptographic components in a graphic design view and simulate their functioning. This contributes to the purpose of sharpening the user’s awareness about the security of different applications. Apart from this, the software also serves as platform to examine scientific concepts, for example peer-based distributed cryptanalysis. With this approach any number of PCs can be interconnected and utilise the joint computing power.
