Aglet 是一个带有一定智能性的移动软件实体,能够自主地从一台主机移动到另一台主机。相比传统的服务器客户端程序具有更大的灵活性,但安全问题一直是需要研究的 重点。在简单介绍了其现有安全特性的基础上,提出了混合利用签名认证、加密和传输层安全协议等技术来完善Aglet 的安全体系。从实验中得证,这样能有效地提高整个系统的安全性和完整性。 关键词:Aglet;移动代理;TLS;安全性 Abstract: An aglet is a mobile software entity with the capability to autonomously move from one host to another. It provides a great flexibility and customizability compared to the traditional lient-server system, but the security problem is always needed to be improved. Based on the nalysis of the current security characteristic in Aglet system, an extension framework is proposed o perfect the Aglet using encryption and Transport Layer Security protocol. From the experiments, an conclude that these can enhance the security and integrity of the Aglet system. Keywords: aglet; mobile agent; transport layer security; security
