Abstract

Digital signal processor (DSP) is a kind of high performance microprocessor specializing for the digital signal processing. Adopting standard C language program design can realize efficiently all kinds of complex digital processing algorithms on DSP. For Logistic 0/1 key sequence with similar-short period, the paper realizes double K-L transformation by standard C language program on TMS320DM6437 DSP platform for producing long-period key sequence. Experimental result shows that this kind of method makes up the short periodicity phenomenon of digital chaotic sequence. More than that, we also realizes greatly image encryption by using the safe key sequence after double K-L transformation on DSP hardware platform.
