摘要
为了增强Excel工作簿的安全,对Excel工作表,研究了数据级的信息安全问题。用面向对象的程序,获取Excel工作表中的字符和数据信息,得出其编码,按"超长密钥流"算法进行加密。并且,在加密与解密过程中,保持了Excel工作表数据格式的无损,也介绍了加密与解密功能的设置。本研究使Excel工作表的信息安全,有了更坚固的底层保障。
The information safety problem of data level of Excel Worksheets is studied to enhance the safety of Excel Workbooks. Application of Object-oriented Program can acquire the character and the data information in Excel Worksheet and get its encode, and then encrypt it with ＂over length password key stream＂ algorithm and keep the form information of Excel Worksheet not changed, the set up of encryption and decryption function is also introduced. The study can ensure the safety of Excel Worksheet and it provides a stronger ~uarantee from the base.
