银行密码系统安全吗？质数（素数）到底有啥用？李永乐老师11分钟讲RSA加密算法

What significance does it take for people to study these mathematics problems so much? Today, I'll give you a sense of the meaning of mathematics.
Let's say we go to the bank to save money and use it to get the password. Then the password is based on mathematics. There is an encryption algorithm called symmetric encryption.
Encryption is a relatively common encryption method in the past. Another typical asymmetric encryption method is called RSA encryption.

The RSA encryption algorithm was created in 1978 by three math professors at MIT and they invented the algorithm. The three names of the algorithm are called RS and A. So it is called RSA algorithm.
The principle of RSA encryption algorithm can be understood in the video. Is there any way to calculate the factor of large numbers?
It is a quantum computer. The factor decomposition of a large number may be calculated in a week. If this is the case, our banking system may be updated or there may be no way to ensure safety. We now know that our bank's system needs to be updated from time to time.
Once our digital certificate is to be re-updated otherwise it is not This is why we need to keep replacing our algorithm and key to ensure our security
