What is a dynamic password?

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.

Dynamic password is a hot spot in enterprise application, and more and more enterprises use dynamic password to protect their VPN, virtualization, servers, network equipment and so on.

Core values:

(1) conforms to the IT security management system;

(2) Providing secure access for end users to enterprise core information;

(3) Reduce IT management expenses related to passwords;

(4) Reduce the probability of forgetting the password, and do not need to remember complicated passwords.

Extended data:

There are three main types of terminals used to generate dynamic passwords: hardware tokens, SMS passwords and mobile phone tokens.

1, 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 inputs the dynamic password when logging in or authenticating the transaction, thus ensuring the security of the system identity authentication.

2. The hardware token is a hardware password card based on time synchronization. It changes the dynamic password every 60 seconds, and the dynamic password is valid once, generating 6-bit /8-bit dynamic numbers.

3. 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 is displayed on the mobile phone LCD screen 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.
