[0055] image 3 A flow chart of the encryption and decryption method provided by the first embodiment of the present invention is shown. refer to image 3 , the encryption and decryption methods include:

[0056] Step S10: the cloud 100 generates a first encrypted script and a first decrypted script.

[0057] The first encryption script is the script used when the client 200 encrypts the original data to generate encrypted data, the first decryption script is the script used when the server 300 decrypts the encrypted data to obtain the original data, the first encryption script and the first The decryption scripts have a mutual matching relationship, that is, the encrypted data generated by the first encryption script can only be decrypted by the first decryption script. Wherein, the first encryption script and the first decryption script are usually javascript scripts, which have the characteristics of being cross-platform and supporting hot update, and of course they can ...

Abstract

The invention relates to the technical field of encryption and decryption, and provides an encryption and decryption method and apparatus, a computer storage medium and an electronic device. The encryption and decryption method is applied to the cloud and comprises the following steps: the cloud sends a first encryption script to a client, wherein the first encryption script is used for encryptingoriginal data to generate encrypted data; the cloud receives the encrypted data from a server; the cloud decrypts the encrypted data by using a first decryption script matching the first encryption script to obtain the original data; and the cloud sends the original data to the server. In the above method, the encryption script is issued by the cloud, and the decryption script is directly storedin the cloud, thereby providing a way for updating the encryption and decryption scripts, which is beneficial to improving the security of the data in an encryption and decryption process. At the sametime, the decryption process is carried out on the cloud, so that the cloud can conveniently preform the verification, and the computing burden of the server can also be reduced.

Description

technical field [0001] The present invention relates to the technical field of encryption and decryption, in particular, to an encryption and decryption method and device, a computer storage medium, and electronic equipment. Background technique [0002] At present, in network-based applications, there are many schemes for front-end data encryption. The more common method is to use javascript scripts to encrypt data in segments, and then encrypt the data to the server for decryption. Because the security of javascript is not high, the encrypted script at the front end can be cracked even in the case of confusion, which brings serious security problems. At present, there is still no effective solution to the encrypted security problem of javascript script. Contents of the invention [0003] In view of this, an embodiment of the present invention provides an encryption and decryption method and device, a computer storage medium, and an electronic device to solve the above-me...
