In the rapidly expanding field of E-Commerce, mobile agent is the emerging technology that addresses the requirement of intelligent filtering/processing of information. This paper will address the area of mobile agent data integrity protection. We propose the use of Secure Agent Data Integrity Shield (SADIS) as a scheme that protects the integrity of data collected during agent roaming. With th...

Given self-protection from an undesirable environmental externality, we examine. under several conditions, the efficiency properties of cooperative and noncooperative behavior. We demonstrate that if self-protection can transfer the externality to another agent, then noncooperative behavior will lead to overprotection. If self-protection filters or dilutes the externality, then noncooperation l...

The protection of mobile agent systems continues to be an active area of research that will enable future applications to utilize this paradigm of computing. Agent systems and mobile applications must balance security requirements with available security mechanisms in order to meet application level security goals. We pose models for viewing security in application contexts that aid the mobile ...

Mobile Software Agents are at the mercy of the agent places they visit on their itinerary. But certain applications have a need for protection of secrecy and integrity of parts of the mobile agents data space. In this paper I will introduce a definition of the term Mobile Software Agent that is derived from a general definition of the term agent and the definition of Wooldridge and Jennings in ...

With the advent of agent technology, the need for security of applications becomes a concern that is beyond classical data security capability and considerations. Without proper security protection especially against a malicious host attack, the widespread use of agent technology can be severely impeded. The Random Sequence 3-level obfuscated algorithm has been proposed by the authors to improv...

SUMMARY A mobile agent is an object that which can autonomously migrate in a distributed system to perform tasks on behalf of its creator. Security issues in regard to the protection of host resources, as well the agent themselves, raise signiicant obstacles in practical applications of the agent paradigm. This paper describes the security architecture of Ajanta , a Java-based system for mobile...
