Implementation of Trust and Reputation Management for Free-Roaming Mobile Agent Security

Mobile agent (MA) technology plays an important role in today's e-world. MA is a program that consists of code and data that move from one host to another host and performs a task on behalf of the user. MA protection becomes essential when it migrates to the remote hosts in a network. Here, trust and reputation management (TRM) is implemented to provide a secure path for free-roaming MA data protection. TRM utilizes a trust-based routing table that is constructed with a trust and reputation value. Various types of attacks, particularly colluded truncation attacks, are avoided by secure routing. Cryptographic algorithms are used to ensure properties such as confidentiality, integrity, etc. Thus, the free-roaming MA retrieves information from various remote hosts in a secure and efficient manner.
