What role does the encryption dog of NC flame cutting machine play

What role does the encryption dog of NC flame cutting machine play


Hello, "dongle" is a combination of software and hardware inserted into the parallel port of the computer (the new dongle also has USB port). Generally, there are dozens or hundreds of bytes of nonvolatile storage space for reading and writing. Now the newer dog also includes a single chip microcomputer. Software developers can check whether the dongle is plugged into the interface through data exchange between the interface function and the dongle (i.e. reading and writing the dongle); Or directly encrypt your own EXE file (commonly known as "package") 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 the dongle is not inserted or does not correspond to the dongle, the software will not execute normally. The main function of the dongle is to protect the software from piracy. There is a certain storage space in it, which can store some data or code. When the program is running, read the data in the dongle to determine whether it is a legitimate user. Because access to the dongle requires a password, there is no need to worry that the data in the dongle will be illegally read and copied. At present, there are about ten brands of encryption dogs on the market. Among them, rainbow encryption dog is an early one in the industry. Its headquarters is in the United States. The company is called SafeNet (saffnet). There are dozens of agents in China. Guangzhou Visai Computer Co., Ltd. is more professional in South China. [Abstract]
