Design and Implementation of SMS Security System for Wireless Environment Yan-Ha1, Hea-Sook Park1, Soon-Mi Lee1, Young-Whan Park1, and Young-Shin Han2 Abstract. This paper aims at developing communication module and application program for client management module and developing database management module and managing wireless communication facilities for server systems. To construct these aims, we have adapted DES algorithm and researched on encrypting and decrypting module development applicable to SMS Security System and optimize module size and processing speed. In addition, the XML technology is applied to encrypt only the contents of the message in a way to reduce the volume of data to process and shorten the time to encrypting. 1. Introduction 1. 1 Background of the Study SMS(Short Message Service) is a two-way mobile data communication service for mobile (cell-phones, PDA) may exchange short messages without additional equipment. SMS is widely used domestically due to the accuracy and promptness and other advantages of SMS, and GSM(Global System Association) reported that 19 billion messages were transmitted per month worldwide last year . In addition, the on-going researches are focusing on the system research and development for M-Commerce by using the advantage of SMS under the mobile Internet environment. However, there are still insufficient efforts in resolving the shortage of SMS, the issues of security (exposing or altering the message). These shortages may become the factors in interfering with the safe e-commerce environment. Therefore, if the security of SMS is strengthened to remove the risks on information exposure and alteration, it would be applied effective on the areas of services on order of goods for M-Commerce and E-Commerce, proceed payment, confirmation of payment, forwarding of electronic receipt and others, services on balance inquiry, transfer, introduction of new financial product on mobile internet banking service, and services on
