Distribution of RSA Public Key with Security Device based Identity for Multi-Agent secured Distributed Computing System

Abstract

In Mobile Agent Technology, interoperability between agents is indispensably to secure the data from malicious agents under Multi-Agent System. To protect data and agents from malicious attacks, the multiagent system essentially needs to offer secure communication and access control mechanisms. Hence the digital signature and cryptosystem of asymmetric key based encryption and decryption provides secure communication and increases the confidentiality of accessing services designated only to a determined group of users. However, for the distribution of public key between agents we need to identify the trusted agent. The identification of trusted agent in a multi-agent platform is a challenging work. The technique of adapting USB Dongle is like a security device, which makes the identity of trusted agent, gives a robust mechanism for the identification of trusted agents in a Multi-Agent secured Distributed Computing System. In addition to that bio-metric based finger print sensor enables the owner's physical contribution to access the data.
