摘要：Mobile agents’ paradigm wide acceptance depends on the ability to overcome its major problem of security. In this context, the major concern is the subtle issue of malicious hosts. Many solutions had been proposed in this area, varying from tamper free hardware to pure software protocols. Nevertheless, neither of them is fully satisfactory. This paper investigates the problem on a novel basis. It develops an incremental protocol giving the opportunity to appreciate the benefit of making weaker hints available (.i.e., information about the lower suspicious character of malicious hosts). Upon these hints and progressively, the protocol can unambiguously confirm the stronger malicious character of hosts by a process of truth enforcement. This paper develops the issues raised by the protocol and validates the protocol efficiency in regard to the weaker hints use to verify the veracity of what we have called explicitly the lower suspicious character of a host.
