Securing Messages in Wireless Channel by Using New Method of Compression

This study attempts to secure the message by using the new method of compression in which the form of the message is completely changed and it is protected against the passive attack so that the sender and receiver of the information are only the hosts who can understand the encoding scheme. In unsecured channels like wireless, the messages are vulnerable to be read by the unauthorized third parity person, for that reason they must be protected. The method can be used for any language but the concentration of the paper is on the security of Chinese message, so that it using Unicode and needs so many bits to be represented in the computer. The Compression is not only useful because it helps for reducing the consumption of expensive resources, such as hard disk space or transmission bandwidth, especially the message that will be send is always saved as the Rich Text file format that has so many overheads and increases the size of original message, but it also used for encoding the message which is exploited for the security.
