A Novel Security Protocol to Protect Mobile Agent against Colluded Truncation Attack by Cooperation

Protecting data of free-roaming mobile agents has drawn much attention in recent years. But no perfect solution has ever been proposed. Many of the solutions are vulnerable by colluded truncation attacks. In this study we analyze available methods, and design a novel protocol by cooperation between two kinds of agents - task agent who transfers freely in the net and secondary agent who transfers passively. It extends traditional one-dimensional chain relation into two-dimensional chain relation. This new protocol can detect colluded truncation attack, and reduce the attack probability.
