The Dynamic Analysis of a Novel Reconfigurable Cubic Chaotic Map and Its Application in Finite Field

Dynamic degradation occurs when chaotic systems are implemented on digital devices, which seriously threatens the security of chaos-based pseudorandom sequence generators. The shows complex periodic behavior, is often ignored by designers and seldom analyzed in theory. Not knowing exact period output key problem that affects application In this paper, two cubic maps combined, have symmetry reconfigurable form circuit. dynamic behavior map corresponding respectively, reasons for weak randomness sequences studied. On basis, optimized, improved. addition, a generator based constructed from point saving consumption logical resources. Through theoretical numerical analysis, solves after digitization makes better performance less resource consumption, lays foundation applying it to field secure communication.
