What are dynamic command tags

Dynamic command tags generate an unpredictable random number combination based on a special algorithm. Each password can only be used once. It is widely used in application fields such as online banking, online games, telecom operators, e-commerce, and enterprises. .

Dynamic command tag is based on a special algorithm to generate an unpredictable random number combination. Each password can only be used once. It is widely used in online banking, online games, telecom operators, electronics Business, enterprise and other application fields.

As one of the most secure identity authentication technologies, dynamic passwords have been used in more and more industries. Because it is easy to use and has nothing to do with the platform, with the development of mobile Internet, dynamic password technology has become the mainstream of identity authentication technology and is widely used in enterprises, online games, finance and other fields;

engaged in domestic and foreign There are also more and more companies involved in the research, development and production of dynamic passwords. Its advantage lies in its rapid and seamless interoperability with various business systems. Its completely independently developed dynamic password identity authentication software system is stable, efficient and supports multiple authentication modes. Its solutions can serve enterprises of different sizes.

Extended information:

Based on the time synchronization between the token and the server, a consistent dynamic password is generated through calculation, based on time Synchronized tokens generally have an update rate of 60 seconds, and a new password is generated every 60 seconds. However, since the synchronization is based on international standard time, the server is required to maintain the correct clock very accurately, and at the same time, the token is The crystal oscillator frequency has strict requirements, thereby reducing the chance of the system losing synchronization;

On the other hand, every time a token based on time synchronization is authenticated, the server will detect the clock offset of the token According to the amount, the time record should be continuously fine-tuned accordingly to ensure the synchronization of the token and the server and ensure daily use. However, due to the different working environments of the token, it is easy to occur in magnetic fields, high temperatures, high pressures, shocks, water immersion, etc. Uncertain drift and corruption of clock pulses.
