Mobile agent technology is promising for e-commerce and distributed computing applications due to its properties of mobility and autonomy. One of the most security-sensitive tasks a mobile agent is expected to perform is signing digital signatures on a remote untrustworthy service host that is beyond the control of the agent host. This service host may treat the mobile agents unfairly, i.e. according to its' own benefit rather than to their time of arrival. In this paper, the authors present a novel protocol, called Collusion-resistant Distributed Agent-based Signature Delegation (CDASD) protocol.
