计算数据域特征值的两种算法

TWO ALGORITHMS FOR CALCULATING THE SIGNATURE VALUE OF DATA FIELD

设计两种计算数据域特征值的算法。此特征值通常是用线性反馈移位寄存器（ＬＦ－ＳＲ）组成的特征分析器得到的．在数据已按字节存放和速度要求不高的场合下，本算法将是十分方便和有用的．

Two efficient algorithms are derived to obtain the signature value of data field.The same value can be obtained by using a signature analyzer composed of the Linear Feedback Shift Register (LFSR). This method is very convenient and useful in many cases.
