【摘要】：移動Agent技術(shù)的誕生,帶來了電子商務領(lǐng)域研究的革命,使智能電子商務成為未來電子商務模式的發(fā)展方向。然而,由于移動Agent的移動性和智能性等特點具有兩面性,它給電子商務研究注入新的活力的同時,也帶來了新的非傳統(tǒng)的安全問題,而這也成為了阻礙智能電子商務進一步發(fā)展的瓶頸。因而,必須要解決移動Agent的安全問題,特別是移動Agent的遷移安全是當前研究的難點之一。 針對移動agent及其遷移過程中面臨的安全問題和現(xiàn)有安全策略的不足,以公鑰加密體制為基礎(chǔ),提出了一種具備容錯和時限機制的移動Agent安全遷移模型SecRoute。 在該安全遷移模型中,采用了強認證體制,并引入了一個可信的第三方平臺。在節(jié)點之間的遷移采取了類似多次握手的請求遷移與確認算法,可以有效檢測遷移中的常規(guī)單點故障,保證遷移的準確性和安全性。同時,在移動Agent遷移執(zhí)行過程中,利用一個可信平臺進行限時執(zhí)行檢測,可以有效檢測惡意主機的重復執(zhí)行和阻塞攻擊。在發(fā)生故障之后,通過冗余備份機制進行故障的恢復,防止遷移中斷,有效提高了遷移的安全性和健壯性。 通過在IBM Aglets平臺上利用Java語言對SecRoute算法進行仿真實驗和結(jié)果分析,證明了算法的有效性和可行性。通過和其他算法的對比分析,該算法在身份驗證、故障檢測和容錯方面都表現(xiàn)出良好的性能。最后,在移動代理電子商務環(huán)境下對該算法測試,驗證了SecRoute算法在應用環(huán)境中的有效性和可行性。
[Abstract]:The birth of mobile Agent technology brings the revolution in the field of electronic commerce and makes intelligent electronic commerce the development direction of the future electronic commerce mode. However, due to the dual characteristics of mobile Agent, such as mobility and intelligence, it not only injects new vitality into the research of electronic commerce, but also brings new non-traditional security problems. And this also became the bottleneck that hinders intelligence E-commerce further development. Therefore, it is necessary to solve the security problem of mobile Agent, especially the migration security of mobile Agent is one of the difficulties in current research. Aiming at the security problems faced by mobile agent and its migration process and the shortcomings of existing security policies, a secure migration model for mobile Agent with fault-tolerant and time-limited mechanism is proposed based on public key encryption system. In this model, a strong authentication scheme is adopted and a trusted third party platform is introduced. The migration between nodes adopts a request migration and confirmation algorithm similar to multiple handshakes, which can effectively detect the common single point faults in the migration and ensure the accuracy and security of the migration. At the same time, in the process of mobile Agent migration execution, using a trusted platform for time-limited execution detection can effectively detect the repeated execution and blocking attacks of malicious hosts. After the failure occurs, the redundant backup mechanism is used to recover the fault and prevent the migration interruption, which effectively improves the security and robustness of the migration. The effectiveness and feasibility of the algorithm are proved by the simulation experiment and result analysis of SecRoute algorithm on the platform of IBM Aglets using Java language. Compared with other algorithms, the algorithm shows good performance in authentication, fault detection and fault tolerance. Finally, the validity and feasibility of the SecRoute algorithm in the application environment are verified by testing the algorithm in the mobile agent e-commerce environment.
