A Secure Transport Model of Mobile Agent Based on Hybrid Encryption

摘要: 該文分析了目前移動代理系統(tǒng)存在的主要安全問題及現(xiàn)有的解決方案，隨后提出了一種基于混合加密的移動代理安全傳輸模型(HESTM)。該模型主要分成兩部分： (1)利用混合加密算法加密移動代理；(2)利用TLS加密通信信道。仿真與性能分析表明，HESTM模型的確能有效地保護移動代理的傳輸安全，從而有效地提高了整個系統(tǒng)的安全性和穩(wěn)健性。該箅法已成功地應(yīng)用在作者開發(fā)的原型系統(tǒng)-基于移動代理的入侵檢測系統(tǒng)中。

Abstract: This article analyzes the main security problems that current mobile agent sys-tems 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 eiRciently pro-tect 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. -
