What is a password? What does a dynamic password mean

A dynamic password is a combination of numbers that changes from time to time. Each password can only be used once, cannot be reused, has higher security, has been used in more and more industries, such as financial industry (bank), e-commerce (**), enterprises, online games, etc., more and more enterprises at home and abroad engaged in dynamic password related research and development and production. It further solves the problem of network information security.

We commonly use the bank dynamic password, which is used to pay for the second confirmation in order to ensure the safety of the customer's funds. When you confirm your payment in Online Banking, you will need to enter the latest digit on your OTP passcode.

A password can be understood as a kind of password, and the role of a password is equivalent to the role of a password.

Hello, a password is a verbal cipher. It is often used to identify friend and foe. Or, verbal commands given in short terms during combat, military training, or gymnastics. Now it also refers to an authentication identifier.

The password seems to be the command, directing things or something.

Summary. Kiss dynamic password refers to a secure authentication mechanism that verifies the user's identity through a unique password generated. Generally speaking, dynamic passwords are temporary, and a new password is generated for each login, and is valid for a short period of time, usually only about 30 seconds.

This verification method is more secure than fixed passwords, which are easy to crack by hackers, while dynamic passwords are different every time, making it difficult for hackers to simulate and guess the correct password. At present, many ** and Internet applications have begun to use dynamic passwords as a way to log in to verify to improve the security of users.

At present, many ** and Internet applications have begun to use dynamic passwords as a way to log in and verify to improve the safety of users who use slag and tremble.

The generation of dynamic passwords is generally generated through some algorithms and keys, and there are two common methods: TOTP and HOTP. TOTP uses timestamps as the basis of the algorithm to calculate the current valid password through the shared key between the user and the server; HOTP, on the other hand, calculates the password by using a pre-set counter and a shared key. In addition, dynamic passwords can also be implemented through mobile apps or hardware tokens, making it more convenient for users to use.

However, OTP tokens are not completely secure, and if a user's phone or token is stolen or lost, it can often lead to account compromise. Therefore, users need to pay attention to the security of accounts and devices while using leather only with dynamic passwords. <>

The five keys to password strategy are to respect socks.

1. Plaintext message

2. ciphertext

3. Key

4. Encrypt

5. Decrypt algorithm

Vigenere password.

Recycle 26 Caesars cipher keys, and reuse them from scratch after each key is used up. Multiple ciphertext tables smooth out the frequency distribution, making cryptanalysis more difficult. The key word is reused so that the key is as long as the plaintext.

Formula: ci = pi + k[i mod m]) mod 26 ki=a z

Key: The key consists of duplicate key words, m is the length of the key word, and the key space is 26 m.

If the key length is short, it can be attacked by the poor. If the key length is long, it can be assumed that the key word length is m, and m key word letters are obtained by m single-letter frequency analysis.

vernam password.

Stream password: based on bits instead of letters.

ci=pi⊕ki

pi=ci⊕ki

Security relies on the randomness of the key. Although the calculation principle is different, the effect can be seen as a scrambled password with the key length of the plaintext.

Dynamic password is based on a special algorithm to generate a random number combination that cannot be used, each password can only be used once, is widely used in online banking, online games, telecom operators, e-commerce, enterprises and other application fields.

As one of the most secure identity authentication technologies, dynamic passwords have been used in more and more industries. Due to its ease of use and platform agnosticism, 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.

Dynamic passwordsSafety 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 enjoy the many benefits brought by informatization, the issue of network security has become a common challenge faced by mankind in the information age, and the issue of network information security has become a top priority.

In order to solve these security problems, various security mechanisms, strategies, and tools are studied and applied. However, even with the use of existing security tools and mechanisms, there are still significant security risks to the network.
