In this paper a secure agent server named JSAS is introduced. J-SAS has an Agent Virtual Machine with the similar functions as a traditional host machine. By assigning passport to agents, authentication, verification of passports, and translation of code to safe version, J-SAS provides a secure environment for executing the agents. Using resource allocation algorithms, ACL and authentication, J-SAS shows a good defensive mood against unauthorized read/ write, denial of service, and masquerading attacks.
