In order to avoid the new security threats to Wireless networking, such as wire tapping and imitating, we give a design of point to point security end system based on a SDIO interface which implements a safe voice communication system. The design and implement of Advanced Encryption Standard (AES) algorithm is described in the first part of this article. Then detailed hardware design and the software design of the SDIO card is shown in Fig.2. The interface design of the PDA which works along with the card is also designed by Fig.4. At the end, some function and performance tests are done according to this system and the results are analyzed through table 1、table 2 and table 3.
