A Secure Transport Model of Mobile Agent Based on Hybrid Encryption

该文分析了目前移动代理系统存在的主要安全问题及现有的解决方案,随后提出了一种基于混合加密的移动代理安全传输模型(HESTM).该模型主要分成两部分: (1)利用混合加密算法加密移动代理;(2)利用TLS加密通信信道.仿真与性能分析表明,HESTM模型的确能有效地保护移动代理的传输安全,从而有效地提高了整个系统的安全性和稳健性.该箅法已成功地应用在作者开发的原型系统-基于移动代理的入侵检测系统中.

This article analyzes the main security problems that current mobile agent systems face with and existing solving methods, then a secure transport model of mobile agent based on hybrid encryption HESTM is brought forward. The model comprises two parts: (1) Using hybrid encryption encrypt mobile agent; (2) Using TLS encrypts communication channel. The simulation and performance analysis show that HESTM can efficiently protect the transport security of mobile agent indeed, thus enhance the security and robustness of the whole system. This algorithm has been successfully applied in authors developed prototype-mobile agent based intrusion detection system.
