Introduction

The cipher is a piece of hardware or software that obtains passwords. The cipher dynamic password is the password generated by the cipher in real time.

Dynamic passwords are passwords that change at any time. Since the password entered each time is not fixed, there will be no loss even if the password is stolen once. For online banking users who have not applied for certificates, banks usually use dynamic passwords to ensure the security of user accounts. When users need to operate funds in their accounts, they need to use dynamic passwords. Dynamic passwords include dynamic password cards, dynamic password tokens and mobile phone dynamic passwords.

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. We are engaged in dynamic password related research and development and production at home and abroad. There are also more and more enterprises. Its advantage lies in its rapid and seamless interoperability with various business systems. Its completely independently developed command dynamic password identity authentication software system is stable, efficient and supports multiple authentication modes. Its solutions can serve different needs. scale enterprise.

For online banking users who have not applied for certificates, banks usually use dynamic passwords to ensure the security of user accounts. When users need to operate funds in their accounts, they need to use dynamic passwords.

Dynamic passwords include dynamic password cards, dynamic password tokens and mobile phone dynamic passwords.

1. Dynamic password card

Dynamic password card is also called scratch card. It looks like a bank card and has a number of strings printed in a matrix form. When customers use e-banking to conduct payment transactions such as external transfers, B2C shopping, and payment, the e-banking system will randomly give a set of password card coordinates.

Security Hazards

With the deepening of the informatization process and the development of computer technology, networking has become a major trend in the development of enterprise informatization. While people are enjoying the many benefits brought by informatization, network security issues have become a common challenge faced by mankind in the information age, and network information security issues have become a top priority.

In order to solve these security problems, various security mechanisms, strategies and tools have been researched and applied. However, even when existing security tools and mechanisms are used, there are still great hidden dangers in network security.

These security risks can be mainly attributed to the following points:

(1) Each security mechanism has a certain application scope and application environment.

(2) The use of security tools is affected by human factors.

(3) The backdoor of the system is difficult to consider with traditional security tools.

(4) Hackers’ attack methods are constantly updated.
