移动的代理有很大的潜力，增加各种电子商务应用程序的实现效益。然而，使移动的代理能够安全地在开放的和不可控的因特网上行进对于保护移动的代理的内容是必要的。最近，已经开发了许多代理结构，其管理为移动的代理提供访问控制机制所需的密钥。然而，这些结构需要大量的移动的代码或沉重的计算负荷。本文提出了一种用于移动的代理环境中的分层访问控制的轻量级密钥管理方法。该方法不仅为移动的Agent提供了访问控制，而且减小了Agent的规模，降低了计算量。
Mobile agents have great potential for increasing the realized benefit for a variety of e-commerce applications. However, enabling the mobile agent to safely travel over the open and uncontrollable Internet is necessary to protect the contents of a mobile agent. Recently, many agent structures that manage the keys needed to provide the access control mechanism for mobile agents have been developed. Nevertheless, these structures require either large amount of mobile codes or heavy computation loads. In this paper, a lightweight key management method for hierarchical access control in mobile agent environments is proposed. This method not only provides access control for mobile agents but also reduces the agent size as well as cuts down the computations cost.
