Based On Ucon Protocol Of Mobile Agent Platform Protection Mechanism Research And Design

Distributed computing is a hot area of current computer science, due to the enhancement of the complex and dynamic network environment, the traditional distributed computing technology is difficult to adapt to these changes.The mobile agent technology is an emerging technology with some intelligence, which is better able to adapt to the dynamic network environment, has become an important part of distributed computing and widely applied in different fields, such as electronic commerce, distributed databases, and workflow.Associated with the development of the mobile agent technology, its security is also increasingly prominent, and the emergences of more and more security problems greatly limit the promotion and application of the mobile agent technology. Issues such as communication security, data and code protection, there are some of the commonly used security program to solve them, but these programs lack the flexibility and comprehensiveness, and no special security mechanisms for mobile agents.Access control played a very important role in the security of mobile agent protection mechanism.The current access control model and the operating mechanism of the mobile agent cannot be a good combination, which cannot provide a comprehensive and secure access control mechanism for mobile agents.In response to these limitations, we will conduct an in-depth study on another access control model-UCON access control protocol.The UCON access control protocol covers the traditional access control model and the digital rights one.By introducing authorization, obligations,conditions, attribute variability and continuous control,UCON has achieved a dynamic and comprehensive access policies and permissions assigned and play a strong role in promoting access control technology and network security technologies.By combining UCON access control protocol,this paper proposes access control security model and communication security model,which are against security issues of mobile agent platform,and detailed design specification and implementation of the model program are given.
