Embodiment Construction

[0027] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0028] A dynamic password provided by the present invention is composed of at least four groups of numbers, including a group of actual door opening passwords, a group of minute time codes, a group of second time codes and a group of password type codes, and the minute time codes are determined by the application password. The second time code is obtained by converting the actual second time when applying for a password, and the password type code is obtained by converting the password validity period and the actual minute time.

[0029] There are two digits for the actual door opening password, two digits for the minute time code, one digit for the second time code, and one digit for the password type code.

Abstract

The invention provides a method for generating a dynamic password, which belongs to the technical field of information security. It solves the problem that the existing dynamic password generation method is single. The generation method of this dynamic password comprises the following steps: S1, the user sends an application signal to the platform to apply for a password; S2, the platform generates the 5th second time code and the 3-4th minute time code; S3, generates the 6th password Type code; S4, generate the 7th digit password application sequence number; S5, generate the 1-2 digit actual door opening password; S6, combine the actual door opening password with the generated 3rd, 4th, 5th and 6th digits to form 6 digits Password; S7. If the password application sequence number is greater than 1, a 7-digit password is formed in step S6; S8. After the sequence is changed by the password sequence transformation algorithm, it is issued to the applicant. The dynamic password of the present invention can be automatically generated according to specific rules according to the time of password application, and has good security.

Description

technical field [0001] The invention belongs to the technical field of information security and relates to a method for generating a dynamic password. Background technique [0002] Dynamic password is an unpredictable combination of random numbers generated according to a special algorithm. Each password can only be used once. It is currently widely used in online banking, online games, telecom operators, e-government, enterprises and other application fields. [0003] Dynamic password is a safe and convenient account anti-theft technology, which can effectively protect the security of transaction and login authentication. Using dynamic password does not need to change the password regularly, which is safe and worry-free. This is an additional value of this technology. It is suitable for internal applications of enterprises and institutions. Especially useful. The generation method of the existing dynamic password is relatively simple, and it is easy for lawbreakers to brea...
