What are the Characteristics of OTP Chips?

The full name of the OTP chip is One-time Password (also known as dynamic password), and according to a special algorithm, an unpredictable combination of random numbers related to time is generated every 60 seconds. Each password can only be used once, and 1440 passwords can be generated per day. Dynamic password is a safe and convenient account anti-theft technology, which can effectively protect transaction and login authentication. Using a dynamic password does not need to change the password regularly, which is safe and worry-free. This is the added value of the OTP chip technology and is particularly useful for applications within the enterprise.This article POROSVOC will share  the characteristics of OTP chips.

What are the characteristics of OTP chips?

(1) No memory required

Forgetting passwords is a headache for many people. With the popularity of network applications, people need to remember more and more passwords. With dynamic passcode cards, users don't have to remember multiple passcodes.

(3) Double insurance

The dynamic password authentication system uses a two-factor authentication mechanism. There is no loss for the user to lose both the dynamic password card and the account at the same time.

(4) Quick information

In the traditional authentication mechanism, the user password is often unknown when it is lost, stolen, or lost, and it can only be noticed after the loss. When a dynamic password token is lost, the user immediately discovers and reports the loss to prevent an accident.

(5) Both inside and outside are "solid"

Among information system intruders, internal intruders account for more than 80%. For e-commerce sites, the weak part of information security is internal prevention. For example, network administrators can also obtain user confidential information through normal rights, which poses a threat to user information security. The dynamic password authentication system completely entrusts the generation and management of keys to the system, minimizes human factors, effectively prevents internal employees from committing crimes, and strengthens system security both internally and externally.

(6) Simple and easy

IC card authentication, CA authentication, and fingerprint authentication all require the cooperation of special terminal authentication equipment and have a wide range of applications. At present, the commonly used USB flash drive also needs to be connected to the computer. At present, many users cannot use it for telephone transactions. Dynamic Password Tokens are also easy to use on devices that can enter decimal numbers.

(7) Fully compatible

The system is relatively independent, with a simple interface, and is easy to interface with the existing e-commerce website authentication system. It uses a dedicated dynamic password authentication server for authentication to ensure the integrity of the existing application system and protect system resources.

Including dynamic password authentication server and backup dynamic password authentication server. The server is the core part of the dynamic password authentication system. It is installed in the computer room and is connected to the local area network through the business system server, providing strong authentication for internal and external users, and accessing system resources according to the authority of the business system. The dynamic password authentication server has its own data security function, the user data is encrypted and stored in the database, and the data exchange between the dynamic password authentication server and the dynamic password management workstation is also encrypted on the Internet by converting the amount. The backup authentication server is a complete backup of the dynamic password authentication server. When the dynamic password authentication server fails or is out of service, it can immediately take over the authentication task.
