1. Bank authentication failure means that when the credit card is swiped, the message "Please bank card authentication" is displayed. The bank verifies whether the user has the right to access the system. Failure in authentication means that access has failed.

2. Authentication is to verify whether the user has the right to access the system. The mainstream authentication method is to use authentication authorization to verify whether the digital signature is correct or not. Traditional authentication is verified through passwords. The premise of this method is that each user who obtains the password has been authorized.

Authentication refers to verifying whether the user has the right to access the system. Traditional authentication is verified through passwords. The premise of this method is that each user who obtains the password has been authorized.

When creating a user, a password is assigned to the user. The user's password can be specified by the administrator or applied by the user.

The weakness of this method is very obvious: once the password is stolen or the user loses the password, the situation will be very troublesome. The administrator needs to re-modify the user password, and the user must be manually verified before changing the password. legal status.

In order to overcome the shortcomings of this authentication method, a more reliable authentication method is needed. The current mainstream authentication method is to use authentication and authorization to verify the correctness of digital signatures.

Logically, authorization occurs after authentication, but in fact, the two are often the same process.

Before explaining what authentication is, let’s first look at what would happen if there is no authentication?

If there is no authentication function, mobile users can access and use any In wireless networks, the interests of operators are not protected, and at the same time, the security of users is also threatened. At the beginning of the development of mobile communication networks, this problem was considered and solved: using user authentication to identify illegal users.

User authentication is to authenticate users trying to access the network and check whether they have the right to access the network. The network can be protected through user authentication to prevent illegal theft; at the same time, customers in the network can be protected by rejecting "intrusions" pretending to be legitimate customers.

However, as the Tao is higher, the devil is higher. I believe you have heard of or personally experienced such an incident. Someone received illegal fraudulent and promotional text messages on their mobile phone, such as "Congratulations on winning the first prize, please pay taxes in advance" and "Our company sells various types of invoices". As a result, they were deceived and lost money.

Some even show that they are from 110. In this case, the user may have accessed a fake network, so the user also needs to authenticate the network.
