A novel free-roaming mobile agent security protocol against colluded truncation attacks

The data security of free-roaming mobile agent is a problem which hasn't been resolved totally, especially in the aspect of keeping away colluded truncation attacks. In this study we use mobile agent's clone, forming a new two-dimensional chain relation among multi-agent to protect the data collected by mobile agent. This new protocol can detect truncation attacks by consecutive malicious hosts, reduce attacking probability, and decrease the damage made by colluded truncation attacks.
