In this paper, we discuss a kind of filter generator whose filter functions have less input bits than the degree of the linear feedback shift register ( lfsr ). by analyzing the structure of the filter generator and its equivalent system, we give out a conditional search algorithm ( csa ) to attack this kind of filter generators
針對濾波函數f （ x ）的輸入比特數m少於線性反饋移位寄存器級數n的濾波生成器，本文通過分析其等價的組合生成器的結構，以及不同節拍上驅動序列的各個符號之間的制約關系，給出了廣義解序列的概念，並提出了類似遍歷二叉樹的條件搜索演算法csa ，用於攻擊該類特殊的濾波序列。 -
After deeply studying all kinds of problems of current actualization methods, we put forward to a new actualization method of the technology of physical isolation on the base of cpld. we make a lot of research on data encryption and describe the design method of the encryption chip on the base of lfsr ( linear feedback shift register ). after putting forward to the whole design procedure, we design an encryption chip on the base of lfsr, which can provide the high - quantity data stream of encrtption
在深入研究了常見物理隔離技術實現方案中存在的各種問題后，提出了一種基於cpld的全新實現方案；同時，對于存儲信息的加密也進行了研究，詳細闡述了基於移位寄存器的非線性組合序列密碼的設計方法，提出了完整的設計流程，並設計了一個基於fpga的非線性組合反饋序列密碼晶元，該晶元能提供高質量的偽隨機密鑰流。 -
Fcsr sequences are the abbreviation for feedback with carry shift register sequences. among these, the most important are maximum - period fcsr sequences, that is, l - sequences
