Description

电子文档的保密装置 Electronic document security device

技术领域 FIELD

[0001 ] 本发明涉及电子文档,特别是一种电子文档的保密装置。 [0001] The present invention relates to an electronic document, an electronic device particularly confidential document. 背景技术 Background technique

[0002] 文档包含有大量的语言文字符号,或称“字符”。 [0002] document contains a large number of symbolic language, or "character." 为保护明文文档的内容不被非法获知,需要对文档中的字符进行加密。 To protect the contents of the document are not expressly illegal informed that the need for characters in the document is encrypted. 传统的加密手段可分为两大类:有规律类和无规则类。 Traditional encryption methods can be divided into two categories: regular class and no class rules. 有规律类加密手段就是按照一定的规则或规律,对明文中的字符进行变换得到密文,从而实现加密的目的。 Regular class of encryption is according to a certain rule or law of plaintext characters ciphertext transformation in order to achieve the purpose of encryption. 此种方法最大的缺点在于,理论上来说任何一种有规律的加密手段都可以通过数学运算而被破解。 The biggest drawback of this method is that, in theory, any regular means of encryption can be cracked by mathematical operations.

[0003] 无规则类加密手段是用一个代码替换另一个字符的加密方法,且代码替换字符的对应关系没有内在的数学规律。 [0003] random replacement class of encryption is an encryption method with a code for another character, and a character code replacement correspondence relationship no inherent mathematical laws. 记载字符和代码之间对应关系的文档称为编码本。 A correspondence relationship between the characters and codes according to the document referred codebook. 这种加密方法的优点是安全性高,缺点是代码和字符之间的转换需要较大的运算量,而且编码本的数据量较大不易安全保存,一旦编码本被泄漏,则所有依赖此编码本加密的文档都遭破解。 The advantage of this encryption method is safe, the disadvantage is that the conversion between the character code and requires a large calculation amount, and a large amount of data encoded according to the present difficult safekeeping codebook is once leaked, all dependent on this encoding this encrypted documents have been cracked.

[0004] 假设编码本的一部分内容如下表1 [0004] The hypothesis part of the codebook shown in Table 1

[0005] 表1 [0005] TABLE 1

[0006] [0006]

Figure CN102096789AD00031

[0007] 要对“ I_L0VE_U ”这段明文字符进行加密,则根据上表1中字符和代码的对应关系,可以把“ I_L0VE_U”转换为代码“ 7395767986699585 ”,然后将这一段代码保存,得到密文文档。 [0007] To "I_L0VE_U" This encrypted plain characters, the table according to the corresponding relationship and a character code, can be "I_L0VE_U" converted into a code "7395767986699585", then a code to save these, ciphertext documents. 密文文档的内容同明文字符完全不相同,起到了加密的效果。 The contents of the document with the ciphertext plaintext completely different character, played encryption effect. 针对密文文档解密时,将密文文档中的内容,根据编码本中代码和字符的对应关系,则可将“7395767986699585”这段密文还原为“I_L0VE_U”,起到了解密的效果。 Decrypting the ciphertext for the document, the document contents of the ciphertext, based on the correspondence and encoding the code characters can be "7395767986699585" This returning ciphertext "I_L0VE_U", played effect decryption.

[0008] 电子文档指的是将语言文字内容中所包含的各个字符(characters,symbol)转换为计算机系统可以识别的代码(code),并将所有的代码保存在存储器中形成的文档(Document)。 [0008] The electronic document refers to the respective characters (characters, symbol) language text contained into code (code) can be identified by the computer system, and stores all code formed documents in a memory (Document) .

[0009] 所述的存储器为光盘、软盘、移动硬盘、U盘、SD卡、集成电路芯片、手机的存储芯片、个人电脑、网络服务器、电子书、或手机等具有存储电子文件功能的设备。 [0009] The memory is an optical disk, a floppy disk, a mobile hard disk, U disk, SD card, an integrated circuit chip, memory chips phones, personal computers, network servers, e-book, mobile phone, or other device having a function for storing electronic files.

[0010] 字符和代码的对应关系形成编码表,目前国际通用编码表有《UTF-8编码表》, ((Unicode编码表》等,国内通用编码表有《GBK编码表》,《GB2312编码表》等不同的编码表, 编码表中的代码称为字符代码。为了便于识别,在编码表中通常采用一个16进位制或者10 进位制的数字来为字符代码命名。上述通用编码表通常以电子文档的形式进行存储和使用。包含有计算机系统的编辑装置可以同编码表相连接,并可以根据编码表中所记载的字符与字符代码的对应关系,将字符同字符代码进行双向的相互转换;或根据编码表中所记载的A代码系统与B代码系统之间的对应关系,将不同代码系统的代码进行相互转换。所述的计算机系统,指的是具有读取或编辑或保存电子文档功能的各种设备,包括但不限于单片机、个人电脑、服务器、手机、家用游戏机、电子书等 [0010] character correspondence between the code forming the code table, the current international standard encoding table has "UTF-8 encoding list", ((the Unicode encoding list ", etc., domestic universal coding table has" GBK encoding list "," GB2312 coding table "and different coding tables, code table code called character codes. for ease of identification, the encoding table is usually employed a number from 16 binary system or 10 binary system named character code above-described universal coding table typically electronically in the form of a document editing device for storage and use with a computer system may be connected to the same encoding appearances, and may be bidirectional character with character code conversion according to the correspondence with the character code character code table described.; or a correspondence between the coding system codes are described in table B and the code system, a code system different code conversion is performed. the computer system having means to read or edit or save the electronic document function a variety of devices, including, but not limited to, microcontrollers, personal computers, servers, mobile phones, home game consoles, e-books, etc.

[0011] 电子文档的加密和解密过程可以借助计算机系统的转换程序来完成。 [0011] encryption and decryption of electronic document conversion program can make use of a computer system to complete. 目前对于电子文档进行加密和解密普遍采用有规律类的加密手段,极少采用无规则类加密手段。 At present, for electronic documents commonly used to encrypt and decrypt the encrypted means law class, and very few no-rules kind of encryption. 而有规律类方法最大的缺点在于保密性不够强,理论上来说只要有运算速度足够快的计算机, 任何一种有规律的加密手段都可以通过计算机的运算而被破解。 And regular class methods The major drawback confidentiality is not strong enough, as long as there is theoretically sufficient computing speed, any regular means of encryption can be cracked by a computer operation. 此外,如果加密和解密所使用的计算机系统的语言环境不相同或加密者和解密者所采用的编码表不一致,可能出现解密后的文档无法正常显示的情况。 In addition, if the computer system is used to encrypt and decrypt the language environment is not the same person or inconsistent coding table encryption and decryption are adopted, the situation is decrypted document can not be displayed properly may occur. 例如针对一段中文明文,加密时采用中文版的Linux 操作系统得到密文,解密时采用的是日文版的windows系统,则可能出现解密后无法正常显示原明文的情况。 For example, some Chinese plaintext, encrypted using the Chinese version of the Linux operating system to get the ciphertext using the decryption is the Japanese version of the windows system, the situation does not display properly decrypted plaintext of the original may occur.
