加密狗是外形酷似U盘的一种硬件设备,正名加密锁,后来发展成如今的一个软件保护的通俗行业名词,实际上
浙大中控加密狗厂家告诉您,"加密狗"是一种插在计算机并行口上的软硬件结合的加密产品(新型加密狗也有usb口的)。一般都有几十或几百字节的非易失性存储空间可供读写,现在较新的狗内部还包含了单片机。
The dongle is a kind of hardware device that looks like a USB flash disk. It was renamed the encryption lock, and later developed into a popular industry term for software protection. In fact, the manufacturer of the dongle of Zhejiang University Central Control told you that the "dongle" is a combination of software and hardware plugged into the parallel port of the computer (the new dongle also has a USB port). Generally, there are dozens or hundreds of bytes of non-volatile storage space for reading and writing. Now the newer dog also contains a single chip computer.
软件开发者可以通过接口函数和软件狗进行数据交换(即对软件狗进行读写),来检查软件狗是否插在接口上;或者直接用软件狗附带的工具加密自己EXE文件(俗称"包壳")。这样,软件开发者可以在软件中设置多处软件锁,利用软件狗做为钥匙来打开这些锁;如果没插软件狗或软件狗不对应,软件将不能正常执行。
Software developers can check whether the dongle is plugged into the interface through data exchange between the interface function and the dongle (that is, reading and writing the dongle); Or directly encrypt your EXE file (commonly known as "shell") with the tool attached to the dongle. In this way, software developers can set multiple software locks in the software and use the software dog as the key to open these locks; If no dongle is inserted or the dongle does not correspond, the software will not execute normally.

加密狗通过在软件执行过程中和加密狗交换数据来实现加密的,加密狗内置单片机电路(也称CPU),使得加密狗具有判断、分析的处理能力,增强了主动的反解密能力。这种加密产品称它为"智能型"加密狗,加密狗内置的单片机里包含有专用于加密的算法软件,该软件被写入单片机后,就不能再被读出。
The dongle is encrypted by exchanging data with the dongle during software execution. The dongle has a built-in microcontroller circuit (also known as CPU), which makes the dongle have the processing ability of judgment and analysis, and enhances the active anti-decryption ability. This encryption product is called "intelligent" dongle. The built-in microcontroller of the dongle contains algorithm software dedicated to encryption. After the software is written into the microcontroller, it can no longer be read.
这样,就保证了加密狗硬件不能被复制。同时,加密算法是不可预知、不可逆的。加密算法可以把一个数字或字符变换成一个整数,如DogConvert(1)=12345、DogConvert(A)=43565。
This ensures that the dongle hardware cannot be copied. At the same time, the encryption algorithm is unpredictable and irreversible. The encryption algorithm can convert a number or character into an integer, such as DogConvert (1)=12345, DogConvert (A)=43565.
加密狗是为软件开发商提供的一种智能型的软件保护工具,它包含一个安装在计算机并行口或USB口上的硬件,及一套适用于各种语言的接口软件和工具软件。加密狗基于硬件保护技术,其目的是通过对软件与数据的保护防止知识产权被非法使用。您有需求就来联系我们
