What is a dynamic password? How to fill it out?

Dynamic cipher is a combination of random numbers that changes according to a special algorithm. The mainstream forms are SMS, hardware token and mobile token. The advantage of dynamic password is that it is easy to use and has nothing to do with the platform. It can be used smoothly through computers, mobile phones and IPAD, and is widely used in online banking, online games and telecommunications.

Just fill in the number received by SMS or the number on the hardware token directly.

Dynamic password technology;

At present, there are three mainstream terminals used to generate dynamic passwords: hardware tokens, SMS passwords and mobile phone tokens.

Sms password

SMS password requests a dynamic password containing 6-digit random number in the form of mobile phone SMS, and the identity authentication system sends a random 6/8-digit password to the customer's mobile phone in the form of SMS, and the customer enters this dynamic password when logging in or authenticating the transaction, thus ensuring the security of the system identity authentication.

Short message dynamic password authentication technology is considered to be one of the most effective methods to solve user identity authentication at present, which can effectively prevent hackers, Trojans from stealing user account passwords, counterfeiting websites and other network problems, resulting in the loss of users' property or materials.

Hardware token

At present, the most popular hardware password card is based on time synchronization. The dynamic password is changed every 60 seconds, which is valid once and generates 6-bit /8-bit dynamic numbers.

Dynamic Password Card/Dynamic Password Card-KingKey 1000 is a handheld terminal based on two-factor dynamic password generation. The terminal randomly generates a new password every minute according to the hardware password seed, time and event, which is very random and unpredictable.

KingKey 1000 needs to be used in conjunction with the corresponding server software, and is widely used in online games, financial software systems, ERP software systems, government e-government systems, military systems, VPN virtual private network systems, financial systems and other software systems that require high password security.

Mobile token

Mobile phone token, also known as mobile phone password card, is a mobile phone client software used to generate dynamic passwords. In the process of generating dynamic passwords, there will be no communication and cost, and there is no possibility of being intercepted in communication channels. As the carrier of generating dynamic password, mobile phone has no influence of arrears and signals.

Because of its advantages of high security, zero cost, no need to carry, obtain and logistics, it is more in line with the spirit of the Internet than hardware tokens. Due to the above advantages, mobile phone token may become the mainstream form of dynamic password authentication token in 3G era.

The essence of mobile phone token is to realize dynamic password technology in the form of mobile phone software. After the software is started, an unpredictable dynamic password will be displayed on the LCD of the mobile phone every minute through the operation of the mobile phone.

Mobile phone dynamic password can run in Windows Mobile, iPhone, android, symbian and other mobile phone operating systems. The key can be tied to the mobile phone. Like the hardware token form of dynamic token, taking Haiyue communication mobile phone token as an example, from a technical point of view, there are two mainstream forms: time-based synchronization and challenge/response.
