FCSR原理及其VHDL语言的实现

Theory and Realization of FCSR Based on VHDL

伪随机序列发生器是序列密码设计中的重要环节 ,F CSR是其中一类重要思想。本文介绍了 F CSR的特性和产生方法 ,并用 V HDL语言予以实现 ,给出 FCSR序列的主程序和仿真波形 ,最后指出需要注意的问题。

The pseudorandom sequence generator is an important tache in the design of the sequence cipher .One kind of the pseudorandom sequence generator is FCSR. The character and the method of generating the FCSR sequence implemented with VHDL are introduced in this paper. The main programme and the simulation wave are supplied and some matters that must be concerned are pointed out at last.
