Using the devaney chaos theory, designed a compound chaotic mapping as the encryption function, and had proven that the track was non-periodic for the initial value of a finite decimal. The authors have designed an encryption algorithm successively according to this, and realized the encryption for sound documents. Afterward the simulation experiment has been set on. They realized the key sensitivity analysis, the statistical analysis, as well as the correlation analysis of definite text and secret text. The experimental result showed that this system has the good cryptology performance, produces the large key space. Meanwhile, it has excellent avalanche effect, resists exhaustion and the statistical analysis effectively.
