An Agent-Based Secure Transaction Protocol with Fair Privacy

To reduce mobile users´ dependence on effective network availability, this paper proposes mobile agent technology in mobile computing applications. This allows mobile users to perform data collection and electronic transactions in a wireless network environment. In an agent-based transaction protocol, mobile agents carry information provided by the user and are able to migrate between hosts to execute tasks. The issue of safety i.e. ensuring the information carried by mobile agents is not modified or eavesdropped on becomes important and cannot be ignored. This paper proposes a secure transaction protocol; mobile agents help users gather information on goods. Since the protocol is tailored to the user´s needs, the security of the application system is comprehensively enhanced. The issues addressed include preserving the privacy of the user´s identity, the integrity of transaction information, non-repudiation and fairness of transactions, and the confidentiality of information exchange.
