3. Sony dongle:
Sony dongle is the first choice for many users because of its simple structure and novel design. In 1950s, Sony's black-and-white TV sold well, but its technical competitiveness was not outstanding, and the quality control of color TV products manufactured afterwards was not satisfactory, which led to huge losses and pushed the company to the brink of bankruptcy.
1967, Sony released Teletron CRT technology developed by Masaru Ibuka himself, which made Sony TV sell well all over the world, and the huge development debt borrowed by Akio Morita from the Japanese Development Bank was paid off within three years. It has become the dominant standard in the field of professional broadcast video, and many broadcast video standards are based on this.
4. Wireless dongle:
Pioneer dongle has advanced technology and many breakthroughs in function. The company's business scope includes the manufacture of musical instruments, musical instrument accessories, wooden handicrafts and hardware accessories.
Technically, the encryption dog format is far stronger than other formats, but Panasonic has won the support of many manufacturers through flexible authorized operation, thus dominating the civilian market. With its technical advantages, wireless power amplifier format has entered the professional field and become the dominant standard in the field of professional broadcasting and video. Today, many broadcast video standards are based on this.

Precautions for the use of encryption dogs:
The software design of encryption lock includes the software design of computer and encryption lock. The software on the computer side is mainly a functional module that provides calls for application software. Comprises an authentication driving module, a session key generation module, an encryption and decryption module and a data exchange module.
Wherein the authentication driving module generates an authentication request, for example, according to time or event. When the authentication event occurs, the application calls other modules to determine the legitimacy of the current application software by communicating with the encryption lock. The session key generation module returns a certain number of pseudo-random numbers to the main program as the session key.
The encryption and decryption module calculates the corresponding ciphertext for the given plaintext and key, or calculates the corresponding plaintext for the given ciphertext and key. The data exchange module sends the data specified in the computer to the encryption lock and receives the data or confirmation signal returned by the encryption lock;
And set the timeout in it. When the timeout number is greater than the specified number, it is considered that the encryption lock is not connected to the parallel port, or the encryption lock is illegal. The program is written in standard C language, which is easy to use across platforms.
