Comparing the Trust and Security Models of Mobile Agents

Mobile agent systems employ a number of security features to address the various threats. Despite this common need for security, there doesn´t seem to exist a generic trust and security model that covers all the levels of their operation and that could be used as a standard. This paper intends to present the advances of modern trust and security models by presenting and comparing the security architecture of four major mobile agent platforms. The conclusions drawn are then used to point out deficiencies of current technology and highlight issues that need to be addressed by future research.
