The RFID and Sensor system has much benefit but simultaneously has some problems such as user's privacy violation. Ubiquitous computing requirement in security that can happen in ubiquitous environment, and by suggesting the direction of security service centered on safe key distribution, certification and sensor node capture defense technology. In the proposed crypto systems we use a new security protocol. For the control of key that can be used for the certification of sensor node or encryption of sensed information, the researchers suggest a key control method and security protocol to defend against sensor node capture by applying PKI method to Hash Lock.
