Abstract
Chaos has good statistical characteristics and is sensitive with initial value which is appropriate for encryption system. Since digital chaos is conducted under the condition of finite precision, which will lead to the degradation of the system and the output sequence will appear periodicity. This paper proposed an improvement for the short period of digital chaotic sequence and designs a new type of digital chaotic sequence generator based on FPGA. Experimental data show that this new cycle of the system output sequence can be set according to the encryption necessary which remedies the short-period phenomenon of digital chaos, so that digital chaotic sequence generator is safe to be applied to the encryption system.
