摘　　要：以非线性组合函数和线性反馈移位寄存器为基础,利用可编程逻辑门阵列进行Geffe流密码设计,并在实验中实现。该密码既能满足密码学领域对密钥序列的高质量要求,又能满足保密通信领域高速度要求。On the basis of non-linear combination of function and linear feedback shift register,by programmable logic gate arrays Geffe stream cipher was designed and realized in the experiment.The password not only can meet high-quality requirements to password key sequence in the field of cryptography,but also meet the high-speed requirements in the field of security communications.
