Problems solved by technology

[0002] At present, the user names and passwords set by people are stored in the same table, and there is a one-to-one correspondence between user names and passwords in this table. The password corresponding to the user name, although the current passwords are mostly hashed, and the specific password information cannot be directly obtained, a single attacker can still know the user's password by cracking the hash value, so the current password setting method has a lot of loopholes. The use of the system brings risks, especially in some cases involving financial information. Once the password is cracked, the user will suffer huge economic losses

Embodiment Construction

[0014] In order to clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific implementation modes.

[0015] Since the user name submitted by the user is stored in the server's data table, when the user registers the user name, first check whether the user name already exists in the data table, so as to ensure that the user name is unique, and then set the password , the server combines the user name and password submitted by the user to form a phrase, hashes the phrase, obtains a key value, and stores the key value in the key-set table.

[0016] When performing authentication, the user enters the user name and password, and the server hashes the phrase composed of the user name and password, and compares it with the key in the key-set. If the key in the database can be matched, the authentication is passed, and the user name Or if there is a discrepancy in the password, the authentication will not be pa...

Abstract

The invention discloses a password setting method for resisting password cracking. The method comprises the following steps: storing a user name submitted by a user into a data table of a server, combining the user name and a password submitted by the user together to form a phrase, performing hash for the phrase to obtain a key value, and storing the key value into a key-set table. According to the above structure adopted by the invention, the user name and the password are separately stored in different tables, the intuitive one-to-one correspondence between the user name and the password can be avoided, even if information of the server is leaked, attackers cannot acquire the password information corresponding to the user name directly through the user name, and thus the vulnerability of existing password setting modes can be eliminated, and the use risks of the user can be avoided.

Description

Technical field: [0001] The invention relates to a password setting method against password cracking. Background technique: [0002] At present, the user names and passwords set by people are stored in the same table, and there is a one-to-one correspondence between user names and passwords in this table. The password corresponding to the user name, although the current passwords are mostly hashed, and the specific password information cannot be directly obtained, a single attacker can still know the user's password by cracking the hash value, so the current password setting method has a lot of loopholes. The use of the password brings risks, especially in some cases involving financial information. Once the password is cracked, the user will suffer huge economic losses. Invention content: [0003] The invention provides a password setting method against password cracking. The method is reasonably designed, and the user name and password are stored in different tables, wh...
