ABSTRACT

Because the information technology is significantly developed, and more data are required to be transmit by wireless

communications, such as: Wi-Fi, Zigbee, Bluetooth and so on. During transmission, data can be easier to be stolen by a hacker.

Therefore, the security of data transmission becomes extremely important. In this paper, we use VB (Visual Basic), to make a platform of visual interface, and verify the correctness when we use the VB program to control (Helicomm, IP-Link 2220H). We connect the Zigbee devices (IP-Link 2220H) with the computer by RS-232 transmission line. Messages or command can be sent from a Zigbee devices connect with a computer to another. During transmission, path information and transmitted message are important to avoid to be stolen. Therefore, we use the hash algorithm to encrypt. On the other word, we use the hash algorithm to hide the all critical message to make the communication in be more secure.

Keywords : Wi-Fi、ZigBee、Hash algorithm
