概要

There has recently been active research on mobile agent technology. Very few, however, address security issues for a practical service model such that a number of service providers are engaged over the heterogeneous network. In this paper, we present a new approach on "access control" to realize global authorization under such environments. In our method, policy files and information related with authentication for an agent are consistently managed and efficiently processed by an authentication server of each network. Furthermore, for the purpose to enhance the security and realize the efficient access control, new interface modules called "secure stub" are proposed. As the result of its evaluation, it can be basically feasible to operate in our proposed system architecture. We believe that the work presented here is significant to the advancement of the existing mobile agent environments supporting secure communications.
