“…The problems in agent security arise when an agent is used in open and unsecured environments [8,3]. One kind of attack by an execution host (malicious host) is spying on the agent's code, data and state [6,11].…”

“…Spying attack by the malicious host on an agent's data or state is difficult to detect, because the attack doesn't leave any detectable trace [6,11,5]. The executing host has to read the agent's code, must have access to the agent's data, and must be able to manipulate the agent's variable data in order to execute the agent [6,5,8]. Therefore, the executing host can see and access all of the agent's code including data and state, and is thus able to hide any traces of an attack, which makes any attempt to address spying attack difficult.…”

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 improve agent security: in this paper, an enhancement to the protection level of this algorithm is proposed. The effectiveness of the obfuscation algorithm is enhanced by addition of noise, which surrounds the true value carried by the agent with false values. A malicious host can thus at best guess the true value carried by the agent.

“…For instance, airlines are now developing technology that will alert passengers, especially frequent fliers, to schedule changes, seat upgrades, and so on, through wireless devices. Recently, the electronic commerce applications provided by mobile communication services include mobile information agents (Mandry et al, 2001;Omicini and Zambonelli, 1998), online kiosks (Slack and Rowley, 2002), government applications (e.g., online selling by the postal service and web-based electronic data interchange in trade applications) and direct online shopping, such as Internet-based (or web-based) shopping malls and Internet-based stock markets. Travel-related and hobby-related sites that provide leisure information are also among the common websites available through mobile communication services.…”

The rapid growth of investments in mobile commerce (M-commerce) to reach a large and growing body of customers, coupled with low communication costs, has made user acceptance an increasingly critical management issue. The study draws upon the task-technology fit (TTF) model as its theoretical basis and its empirical findings to pragmatically explain the key factors that affect the performance and user acceptance of M-commerce. A total of 110 usable responses were obtained. The findings indicate that the task, technology, and individual user characteristics positively affect tasktechnology fit and M-commerce usage. The task-technology fit and Mcommerce usage are the dominant factors that affect M-commerce performance. The result points out the importance of the fit between technologies and users' tasks in achieving individual performance impact fi-om M-commerce. This paper identifies pertinent issues and problems that are critical in the development of M-commerce.Mobile commerce is an emerging discipline that involves mobile devices, middleware, protocols, and wireless networks. Internet-based M-commerce has received considerable attention because of its potential organizational impact. Various business communities have announced plans for Mcommerce enhancements in business transactions, as mobile telephony now allows the potential platform for unprecedented penetration of the mobile communication services. In addition, a great number of organizations have used mobile communication services and M-commerce for business purposes in order to stand a better chance of achieving their competitive advantage. For instance, NTT DoCoMo, Vodafone, Verizon, Sprint PCS, and AT&T Wireless provide "cyber-mediation" and great efficiency in supplies and marketing channels through mobile commerce. The benefits of an M-commerce include: more efficient payment systems, reduced time to market new products and services, improved market reach, and customization of products and services (Barnes, 2002;Senn, 2000).M-commerce applications involve transmitting payment details, requesting information, receiving specific content, or retrieving status information over mobile communication devices. For instance, airlines are now developing technology that will alert passengers, especially frequent fliers, to schedule changes, seat upgrades, and so on, through wireless devices. Recently, the electronic commerce applications provided by mobile communication services include mobile information agents (Mandry et al., 2001;Omicini and Zambonelli, 1998), online kiosks (Slack and Rowley, 2002), government applications (e.g., online selling by the postal service and web-based electronic data interchange in trade applications) and direct online shopping, such as Internet-based (or web-based) shopping malls and Internet-based stock markets. Travel-related and hobby-related sites that provide leisure information are also among the common websites available through mobile communication services.

This paper presents an approach for the dynamic management of the content of several Universal Description, Discovery, and Integration (UDDI) registries. By content, it is meant the announcements of Web services that providers post on various distributed UDDI registries. Unlike other initiatives in the field of Web services, our concerns are the following: availability of several UDDI registries, no predefined communication infrastructure between the UDDI registries, and no centralized component to coordinate the UDDI registries. The solution presented in this paper integrates users and software agents into what we call messengers. When a user is in the vicinity of an UDDI registry, his software agent, which resides in his mobile device, interacts with that registry. The objective is to submit the details on Web services that are stored in the mobile device.
