A trustworthy mobile agent infrastructure for network management

Despite several advantages inherent in mobile-agent-based approaches to network management as compared to traditional SNMP-based approaches, industry is reluctant to adopt the mobile agent paradigm as a replacement for the existing manager-agent model; the management community requires an evolutionary, rather than a revolutionary, use of mobile agents. Furthermore, security for distributed management is a major concern; agent-based management systems inherit the security risks of mobile agents. We have developed a Java-based mobile agent infrastructure for network management that enables the safe integration of mobile agents with the SNMP protocol. The security of the system has been evaluated under agent to agent-platform and agent to agent attacks and has proved trustworthy in the performance of network management tasks

Migration control for mobile agents based on passport and visa

Research on mobile agents has attracted much attention as this paradigm has demonstrated great potential for the next-generation e-commerce. Proper solutions to security-related problems become key factors in the successful deployment of mobile agents in e-commerce systems. We propose the use of passport and visa (P/V) for securing mobile agent migration across communities based on the SAFER e-commerce framework. P/V not only serves as up-to-date digital credentials for agent-host authentication, but also provides effective security mechanisms for online communities to control mobile agent migration. Protection for mobile agents, network hosts, and online communities is enhanced using P/V. We discuss the design issues in details and evaluate the implementation of the proposed system

Integrity protection for code-on-demand mobile agents in e-commerce

The mobile agent paradigm has been proposed as a promising solution to facilitate distributed computing over open and heterogeneous networks. Mobility, autonomy, and intelligence are identified as key features of mobile agent systems and enabling characteristics for the next-generation smart electronic commerce on the Internet. However, security-related issues, especially integrity protection in mobile agent technology, still hinder the widespread use of software agents: from the agent’s perspective, mobile agent integrity should be protected against attacks from malicious hosts and other agents. In this paper, we present Code-on-Demand(CoD) mobile agents and a corresponding agent integrity protection scheme. Compared to the traditional assumption that mobile agents consist of invariant code parts, we propose the use of dynamically upgradeable agent code, in which new agent function modules can be added and redundant ones can be deleted at runtime. This approach will reduce the weight of agent programs, equip mobile agents with more flexibility, enhance code privacy and help the recoverability of agents after attack. In order to meet the security challenges for agent integrity protection, we propose agent code change authorization protocols and a double integrity verification scheme. Finally, we discuss the Java implementation of CoD mobile agents and integrity protection

Cryptography Based Hybrid Security Architecture for Mobile Multi Agents

Distributed Computing is the current area of research. Many researchers are working in area of Distributed Computing and trying to find a solution for the security and other issues. In Distributed Computing the mobile agents are the very important thing. When different mobile agents work in the same environment simultaneously it becomes a very important issue. Mobile agents have automatic, pro-active, and dynamic problem solving behaviors. However, scope of this paper is limited to analyze the existing security approaches for Mobile Multi Agent System. Security issues of mobile agent address the problem of securing and protecting agents from the attack of malicious hosts and other agents as well as securing the host from attack of malicious agents. This paper introduces a new approach of security for agent from other agents. Paper discusses Cryptography Based Hybrid Security Architecture with trust and reputation named CBHSA. It breaks the security of MA in two parts. The first level of security is work on the MA and second level of security is maintained on network. The model CBHSA, its different components and security of MA during movements around the network are discussed in this paper. This paper emphasis on the security of MA’s during migration within the network or outside the network

Secure e-transactions using mobile agents with agent broker

This paper presents an e-transactions protocol using mobile agents. However, when mobile agents travel to a number of servers for searching optimal purchase for the underlying customer, the mobile codes should be protected. We integrate a secure signature algorithm with the e-transaction algorithm to maintain the security. In addition, an agent broker is involved in the algorithm that will help to reduce the communications among the mobile agents, the customer, and the servers. We have presented security and privacy analysis for the proposed protocol

A Security Architecute for Mobile Agent Based Creeper

Mobile agents are active objects that can autonomously migrate in a network to perform tasks on behalf of their owners. Though they offer an important new method of performing transactions and information retrieval in networks, mobile agents also raise several security issues related to the protection of host resources as well as the data carried by an agent itself. Mobile agent technology offers a new computing paradigm in which a program, in the form of a software agent, can suspend its execution on a host computer, transfer itself to another agent-enabled host on the network, and resume execution on the new host. Mobile Agent (MA) technology raises significant security concerns and requires a thorough security framework with a wide range of strategies and mechanisms for the protection of both agent platform and mobile agents against possibly malicious reciprocal behavior. The security infrastructure should have the ability to flexibly and dynamically offer different solutions to achieve different qualities of security service depending on application requirements. 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.A security solution has been introduced, which protects both the mobile agent itself and the host resources that encrypt the data before passing it to mobile agent and decrypt it on the visited host sides i.e. it transfers the URL to the Mobile Agent System that will pass that encrypted URL to the server where it will be decrypted and used. The methods of Encryption/Decryption used are a Public-key Cipher System and a Symmetric Cipher System that focuses on submitting data to the server securely. The proposed approach solves the problem of malicious host that can harm mobile agent or the information it contain
