摘要: 自移動(dòng)代理提出以來(lái)，安全性問(wèn)題一直是制約其廣泛應(yīng)用的一個(gè)最主要的因素。作為分布式C/S計(jì)算模式的延伸，目前備受關(guān)注的多移動(dòng)代理協(xié)作為提高整個(gè)移動(dòng)代理系統(tǒng)安全性提供了一個(gè)新的思路。該文通過(guò)分析基于拉格朗日插值的密鑰分割和多重簽名方案應(yīng)用于多移動(dòng)代理系統(tǒng)中出現(xiàn)的問(wèn)題，給出了一個(gè)改進(jìn)的、更有實(shí)際應(yīng)用價(jià)值的算法。最后，給出了一個(gè)基于此算法的電子交易的案例。

Abstract: Since the introduction of Mobile Agent (MA), security is always an important issue for its restriction to the MAs wide-application. As the extension of distributed Client/Server computing, the present idea of multiple mobile agents gives a new way for increasing the security of the whole mobile agent system. In this paper, problems are firstly discussed in detail when applying the secret splitting scheme based on Lagrange interpolation and the subsequent multiple-signature scheme into Multiple Mobile Agent System (MMAS). Secondly, an improved and more practical scheme for the MMAS is proposed. An e-business case based on this scheme is presented at the end of this paper. -
