SPMH: A Solution to the Problem of Malicious Hosts

摘要

In this paper, a solution to the Problem of Malicious Hosts, named SPMH, is suggested. At first, Mobile Agent Blackbox Construction Method based on Loureiro's Protocol (MABCM-LP) is suggested to convert a mobile agent into a Mobile Agent Blackbox (MAB) which makes the mobile agent difficult to be understood and tampered by malicious hosts. At the same time, a Protocol Tracing the Inputs/outputs and Results (PTIR) is developed to trace the mobile agent running at a host, which can be used to detect and prove the attacks by malicious hosts. It is proved that this solution is secure, correct, and robust. It is found firstly that the detection method and the prevention method are complementary to each other, and this is the first solution that integrated both of these two methods too.
