Abstract Mobile Agents are soft wares migrating from one node to another to fulfill the task of its owner. Mobility introduces two major challenges in front of mobile agent namely reliability and security. As the agent moves from one node to another the goal to complete its task safely is difficult to achieve. Mobile agents are no longer a theoretical concept; much architecture for their realizations has been proposed. However, it has to be confirmed that any failures (machine or agent) do not lead to blocking of agent together with the security issues. This paper proposes a model which deals with both the problems; Fault Tolerance and Security, further it also adds atomicity to mobile agents execution i.e. either all the goals are achieved or none is achieved. This paper proposes a Hierarchal model which uses the concepts of object oriented technology, grouping, atomicity and authentication to deal with the blocking problem and security issues.
