Abstract

Remotely executing mobile code introduces a plethora ofsecurity problems. This paper examines the "external agentreplay" attack, identifies the notion of one-way programstate transitions, describes the use of monotonic variablesas a practical method for detecting these attacks, examinesthe more general problem state modification attacks, and introducesthe use of "results verification vectors" to protectagents from attack.
