Dongle, also known as encryption lock, is used for software and hardware encryption products such as computers, intelligent hardware devices, industrial control machines, cloud systems, etc. Through the dongle management software authorization, software developers can prevent unauthorized use or resist the threat of piracy, and protect source code and algorithms.
Function of dongle
The dongle is unique and used to verify the use of authorized software or algorithms. Whether it is a single application authorization or a complex application authorization, Weibo dongle can meet different encryption application needs for software in different fields.
Single user dongle
A stand-alone user, as the name suggests, is a set of software that can only be used by one user, that is, the equipment hardware used by the user cannot be replaced at will, otherwise the software authorization will be invalid. The stand-alone license is used on the local machine or on the locally connected cmdongle dongle. The software runs on the same computer.
Network user dongle
The application of codemeter network dongle can meet the needs of users for network encryption. For example, customers want to insert the encryption lock into a server in a network interconnection environment, and then let all other user machines open the encryption program on their own machine by accessing the encryption lock on the server.
The network license is located on a central server on the network. PC software uses it as a floating license. It is mainly used as an emergency license in the field of embedded hardware. The license in cloud network only plays a subsidiary role.
Multiple interface dongles
Zheda central control dongle personnel believe that with the arrival of the era of intelligent manufacturing and intelligent hardware, the traditional parallel port and even USB port gradually fade out of the sight of users. Many hardware devices do not even have external interfaces for security, so the form of dongles will keep pace with the times.
Whether it is a common USB port or type-C, various SD cards and other dongles will become increasingly popular. For the intelligent hardware industry, there are chip type dongle products, which meet the software developers' encryption software needs from the hardware level.
At the same time, the virtual dongle is also used as a supplement to realize the uniqueness of the dongle by binding hardware information, so as to achieve the purpose of protecting software products.
