Access control using mobile agents

Recent days, the areas of internet and network computing recognize a fast development, especially with distributed computing and efficient storage technologies that make sharing and diffusion of system resources more easier. However, if the information system didn´t adopt a security policy it may undergo serious damages. In this paper, we will propose a logical security scheme based on an access control policy. We will use the RBAC model applied with mobile agent paradigm to ensure authentication and identification of system entities, as well as to guarantee confidentiality and integrity of data involved in the scheme.
