7、l-phones, PDA) may exchange short messages without additional equip- ment [1-2]. SMS is widely used domestically due to the accuracy and promptness and other advantages of SMS, and GSM(Global System Association) reporte

8、d that 19 billion messages were transmitted per month worldwide last year [3]. In addition, the on-going researches are focusing on the system research and development for M- Commerce by using the advantage of SMS unde

10、nterfering 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 o

17、e client performs the functions of message management and transmission, user and group management. If the client wishes to transmit the message, it logs in on the server, prepares and encrypts the message and the encryp

18、ted message is transmitted to the server. The message prepared at this time becomes the encryption with the secret key of the client. If another client receives the messages from the server, receive the encrypted mess

19、age after logging in. The message encryption in its own secret key is decrypted. The message management function of server is largely divided into two stages. Server decrypts the encryption message transmitted from the

20、 client, then encrypts again with the secret key of the receiver to store in the database. Server makes the contents of transmitting messages unable to read. If the receiving client wants the message reception, the en

21、crypted message is forwarded after the client certification. At this time, the secret key of the XML Manager encrypts the message. If the receiv- ing client wishes to receive the message from the server, log in first an

22、d then use the individual secret key to decrypt the encrypted message. 4 Implementation The server of the developed SMS security system is implemented on the computer with Intel Pentium IV 2GHz 256 DDR RAM, and the

23、development tool is used of Visual Studio 6.0. And, in order to develop the client program, the Embedded Visual Studio 3.0 and Pocket PC SDK are used on the above PC. And, in order to test the program, the server prog
