| Summary: | 碩士 === 明新科技大學 === 電子工程研究所 === 97 === While the digital communication technology has evolved quickly, the cryptography has become an important topic. The goal of this paper is to utilize a chaotic scramble algorithm characteristic for encrypting and deciphering to wireless communication. First, we constructed a hyper-chaotic sequence table written in Visual C++ perform from Hex scramble algorithm. This table was stored in an 8 bit MCU data ROM. Sound encrypting and deciphering are achieved by mixing the sound signal sampled by an 8-bit timer clock and the hyper-chaotic sequence table. A low-cost 8-bit MCU can perform up to the task. The wireless transmission is carried out by a 2.4G RF module.
This paper can be divide into three sections including Hex scramble algorithms of Visual C ++ perform, 8-bit MCU (EPG3231 + AM29LV800), and 2.4G RF module (RF24DT-10DSUJA).
