The Control System Of Computational Node In A Grid System For Cryptograph Computing: Design And Implementation

The development of computational tools and platforms promotes the development and research of Cryptograph algorithms. The Grid computing is a new computational technology. Using the technology of Grid computing can form a virtual super computer, so applying the Grid computing to Cryptograph Computing has much significance.The paper analyzed some computing tasks correlative with Cryptograph algorithms, and discussed some Cryptograph algorithms' demand for new computational technology. One computer cannot execute some tasks, so the paper analyzed the possibility of using the distributed system to execute some of the tasks correlative with Cryptograph algorithms. After reviewing the development of the computational technology, the paper demonstrated that it is reasonable to apply the Grid to Cryptograph computing. Based on the design of the Cryptograph Computing Grid, I designed and implemented the Computational Node Module of a distributed system for Cryptograph Computing. The system is responsible for the executing of the atom sub-task and sends back the result.The paper also described the technologies used in the computational node, their advantages, and their applications. XML, BASE64, SOAP, JNI, Multi-Thread and other technologies were used in the project. Using these technologies make the module of computational node easy, efficient and extendible. As a part of the Grid system for Cryptograph Computing developed by our whole group, the module got very good effect when carrying through the test of DES- Brute-force. The Distributed computing for other Cryptograph computing can also be carried out by the system.
