| 摘 要： | 本文给出了一种基于软件实现的透明码生成的快速算法。字节是Ｃ语言中所能处理的最小数据单元，因而对字节的处理（包括存取、运算等）有着位处理无法比拟的优点。根据这一特点，该算法以字节为单位，通过查表方式，快速生成（和还原）透明码。从而避免了以位操作所带来的时间开销较大的缺点

| Abstract: | This paper presents a fast algorithm for transparency based on the software language. Byte is the minimum unit in processing of C language, so the byte processing which includes access and operation has an advantage which the bit processing can not catch up. According to this characteristics the algorithm processes the source data byte by byte by looking up table to get the transparency code and avoids the deficiency because of the lager overhead brought by the bit operations. |
