摘要：POS system is a supply net administration system for customer management. It becomes an essential element in distribution industry to construct database, and uses XML-Encryption to complement PKI techniques and standards for security. POS system has four advantages. First, it does not have to be certificated and transmit data every time because there is no server. Second, it can integrate database by using XML and improve portability of program itself. Third, transmitted data is safe because of XML-Encryption. Fourth, processing speed will be faster because it gathers data from data transmission. All systems should be designed by considering security level to reduce non-necessary burdens. The concept of security level management was developed by Dr. Tai-hoon Kim a few months ago, and this paper used this idea. In this paper, Security Level 1st environment was considered to design POS systems.
