[0059] 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:

[0060] Step S10: the cloud 100 generates a first encrypted script and a first decrypted script.

[0061] 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 device. The encryption and decryption method is applied to the cloud andcomprises the following steps: the cloud sends a first encryption script to a client, the first encryption script is used for encrypting original data to generate encrypted data; and the cloud sends afirst decryption script matching the first encryption script to a server, and the first decryption script is used for decrypting the encrypted data. In the above method, the encryption and decryptionscripts are all issued by the cloud, thereby providing a way to update the encryption and decryption scripts, which is beneficial to improving the security of the data in the process of encryption and decryption. At the same time, since the cloud is only responsible for providing the encryption and decryption scripts, the real encryption and decryption process is still carried out on the client and the server. This method is suitable for application to the privatized environment of the enterprise, and the enterprise does not have to worry about the leakage of the private data.

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. Background technique [0002] At present, in network-based applications, there are many schemes for front-end encryption of data. The more common one is to encrypt data in sections with javascript scripts, and then encrypt the data to the server for decryption. Due to the low security of javascript, the front-end encrypted script can be cracked even in the case of confusion, which brings serious security problems. At present, in the enterprise privatization environment with high security requirements, there is still a lack of effective A solution to the encryption security problem of javascript scripts. Contents of the invention [0003] In view of this, an embodiment of the present invention provides an encryption and decryption method and device to solve the above technical problems. [0004] To achie...
