Abstract
Applying chaos theory to the encryption scheme has become a hot spot. Although lots of chaotic maps have been proposed, they don’t have advantages in all respects. In this paper, the typical one-dimensional Logistic map and two-dimensional Henon map are studied. The digital output sequences of Logistic map and Henon map can be generated by building their models on DSP Builder platform. And the sequences are tested and compared according to the statistical properties, including balance test, run test and autocorrelation test. Meanwhile, run the transformed VHDL projects in Quartus II environment to compare these two kinds of resource utilizations. The results show that digital Henon sequences have better pseudo-randomness, but Logistic project uses less hardware resources.
