The Research And Implementation Of Security Service In Grid Service System Based On SOA

The grid develops after Internet and Web,It is the third generation Internet application, it is aim to integrate the computing resource, the memory resources, the correspondence resources, the software resource, the information resource and the knowledge resources . The grid connecting with high speed internet form a virtual environment , realize resources share and co-work on virtual environment with high propertie.The grid establish on public Internet which is much open and heteromerous. Except for considering security problem of traditional Internet, lots of new features bringing security problems in the grid computation environment has to be considered, such as users and resources could change dynamicly, process is asked to start when computing, applicate or release resources. The grid security is the most important thing in the grid computation .It could prevent to be falsely claim to be legal users through security Authentication, Private Key protection. and grant legal users authority to access data and execute operations, and prevent data from illegal access and modified, etc.This article has realized the Security Service on the foundation of The Research and design of Grid Service System Based on SOA. The target of the platform is the user uses the browser page, can use each kind of service which the grid provides, the actual structure of the grid is transparen to the user. Through carries on the thorough study and the research to the grid security and grid security infrastructure GSI, analyzes based on the GSI security authentication process, definited grid security service resources on GT4, uses Java Cog Kit to map the grid security service in the Java development frame, carrid on abstractly to the grid security service (requests certificate service, signs certificate service, generates proxy service), packing the GT4 security connection to the Web service and the service connection under the J2EE environment, makes the service level and the first floor realizes specifically separates, independence from the first floor grid platform, has the good extendibility and the probability, enhanced the the degree-of-freedom of the J2EE exploiter to use these connections continue to develop the J2EE service.
