Abstract

Concordia provides a robust and highly reliable framework for the development and execution of secure, mobile agent applications. Concordia incorporates many advanced security and reliability features beyond the basic functionality found in other mobile agent systems. Concordia provides a rich security model that can be used to allow or deny access to system resources down to a very fine level of granularity and that protects agents and the information they carry from tampering or unauthorized access. The system utilizes transactional message queuing to provide reliable network transmissions. Further, Concordia uses proxy objects and a persistent object store to insulate applications from system or network failures. This paper discusses the design and implementation of these features.
