Abstract: Authentication technology acting as the measure of information security plays an important role in network communication. While private information is transferred directly or indirectly through authentication sessions in traditional way, it is very likely to be leaked through bugs of the certification system or stolen by the anti-system application. This paper designs a new kind of authentication model based on the noise-guided two-dimensional hyper-chaotic synchronization mechanism, in which only random noise signal is transferred over the network instead of keys or passwords to prevent the private information leaked or stolen. The synchronization algorithm is implemented both on field programmable gate array (FPGA) and PC, which makes up a cross-platform testing system. Tests show that the model runs correctly and safely.
