Embodiment Construction

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0046] In the prior art, data encryption transmission methods can be divided into two types: one method is to install security controls on the browser side; the other method is to encrypt keys and data by using encryption algorithms through software program codes. Traditional application encryption generally uses security controls or the code of the program itself to encrypt, and then encrypts the data through a certain encryption algorithm and transmits it to ...

Abstract

The invention provides a dynamic encryption safe login method and device. The method comprises the steps of: sending a random ID request to a user side accessing an application, and then receiving a verification code dynamically generated by the back end of the application; verifying the verification code, and if the verification is passed, generating a key according to the ID request; and obtaining encrypted user data by using the key and sending the encrypted user data to the back end of the application, so that the back end of the application verifies and logs in the encrypted user data. According to the invention, the segmented dynamic encryption transmission data starts from a security perspective; the possibility that the whole data is cracked after being stolen is avoided, the situation that the data is easy to crack due to the fact that encryption strings transmitted each time are the same under the condition that the same user logs in for many times is avoided, and the situation that the input of the user is intercepted and monitored after a malicious program is implanted is avoided. Therefore, the safety of data transmission of the user and the application is further improved, and the sensitive information of the user and the application can be safely transmitted and timely processed.

Description

technical field [0001] The present application belongs to the technical field of data communication transmission, and in particular, relates to a dynamic encryption security login method and device. Background technique [0002] In the era of big data, systems and programs often need to go through the link of data transmission, and data transmission provides great convenience and efficiency for data applications. At the same time, there are also security risks in the process of data transmission. At present, the common data encryption transmission methods in the industry can be divided into two types: one method is to install security controls on the browser side; the other method is to use encryption algorithms to encrypt keys and data through software program codes. Traditional application encryption generally uses security controls or the code of the program itself to encrypt, and then encrypts the data through a certain encryption algorithm and transmits it to the backen...
