Recently, much research has been actively conducted for a new kind of network environment ubiquitous computing. This paper will define the essential technology called “ad hoc network” and the smart-tag technology required by a ubiquitous environment. We will describe how to apply smart-tag-related Radio Frequency Identification(RFID) research for Bluetooth, a local-area wireless-communication technology. In order to implement RFID technology for the ubiquitous-computing infrastructure, a number of important technology factors and structures should be considered. These include the realization of low-priced tags and the provision of technical service for the tag’s security. For the passive RFID tags, the functions of each RFID tag and maintenance service should be considered to guarantee the price efficiency. As for the active RF tags’ support of local-area wireless communication, one of the main issues is enhancing the level of security. This paper will present secured RF-tag service for the RF and Bluetooth modes for local-area wireless communication. A method of applying the generated service to the EPC code developed by MIT will also be suggested.
