摘　　要：身份认证技术作为保障信息安全性的手段之一,对于提高网络通信安全性具有重要意义。传统身份认证技术在通信过程中会直接或间接地传输用户相关的机密信息,由于认证系统本身存在漏洞,并且反制技术逐步升级,这些信息很容易被泄露或窃取。参照噪声引导的二维超混沌同步方程,设计实现了一种新型的身份认证模型,可以在认证通信中仅传输随机噪声信号,不发送密钥或口令,从而避免信息被泄露或窃取。分别在现场可编程门阵列(field programmable gate array,FPGA)和PC上实现了同步算法,构建了跨平台测试环境,验证了该模型的安全性和准确性。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 tradi- tional way, it is very likely to be leaked through bugs of the certification system or stolen by the anti-system applica- tion. 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.
