As RFID technology is becoming ubiquitous, the secunty of these systems gets much attention. Its fields of usage include personal identification, supply-chain management systems, and many more. Many kinds of RFID tags are available on the market which differ both in storage, and computational capacity. Since by standard IT means all the tags have small capacities, the security mechanisms which are in use in computer networks are not suitable. For expensive tags with relatively large computational capacities many secure communication protocols were developed, for cheap low-end tags, only a few lightweight protocols exist. In this paper we introduce our solution, which is based on the least computation demanding operator, the exclusive or function. By introducing two tags instead of one in the RFID system, our scheme provides security solutions which are comparable with those provided by the lightweight protocols. In the meantime, our scheme does not demand any computational steps to be made by the ta.

The customer of massage chair is expanding day by day from middle age to all ages. In 2018, the market size was 700 billion KRW, an increase of 30 times over 10 years. However, most related SMEs suffer from excessive competition by the market monopoly of some major companies. In this situation, in order for a related company to survive, it is necessary to steadily research and develop new products. Founded in 2009, company L produces massage chairs for health and relaxation of customers. L's products use a sound wave vibration module that is favorable for human body, unlike other products that use vibration motor type. However, frequent breakdowns of massage chair due to the vulnerability of plate (leaf) springs, which play an important role in sound wave vibration modules, made sap its competitiveness. In this paper, we propose a method to design desirable plate spring structure by sequentially experimenting with five different plate springs. The results of this study are expected to contribute to improve the quality of plate spring and the reliability of sound wave vibration module. In the future, it is necessary to find a way to use it in the development of foot massage or scalp management device as well as continuous research to find optimal plate spring structure through various analysis.
