Problems solved by technology

However, the existing technology mainly has the following problems: 1. The key needs to be negotiated by the two parties of the data transmission in advance. The usual operation method is to use a high-level language to write the key in the encryption code, and anyone can view it through decompilation The key stored in the encrypted code makes data encryption meaningless; 2. When using a symmetric encryption algorithm, the same key is used for encryption and decryption, and the key is easily leaked, making data transmission less secure; 3. , When using asymmetric encryption algorithm, encryption and decryption will take a long time, which will affect the timeliness of data transmission

Embodiment Construction

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. 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.

[0030] At present, the encryption of network data usually adopts symmetric encryption algorithm or asymmetric encryption algorithm. Taking the symmetric encryption algorithm as an example, the client and the server negotiate the key of the encryption algorithm in advance. When the client initiates a data request, it uses the local key key to symmetrically encrypt the data to be sent. The key ...

Abstract

The invention provides a data processing method and device, and the method comprises the steps: randomly generating first character data when a client transmits a data request to a server, generating a first value and a first vector according to the first character data, generating a first timestamp, and generating a symmetric key according to the first timestamp, the first value and the first vector; encrypting and compressing to-be-sent data by using a symmetric key, encrypting the symmetric key by using a public key, respectively encoding the encrypted and compressed to-be-sent data and the encrypted symmetric key, putting the encoded data into a request body of a data request, and then sending the encrypted data request to a server. According to the invention, the security of data transmission can be improved, and the timeliness of data transmission is ensured.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a data processing method and device. Background technique [0002] With the continuous development of Internet technology, the security of network data transmission is becoming more and more important. At present, the encryption of network data usually adopts symmetric encryption algorithm or asymmetric encryption algorithm. However, the existing technology mainly has the following problems: 1. The key needs to be negotiated by the two parties of the data transmission in advance. The usual operation method is to use a high-level language to write the key in the encryption code, and anyone can view it through decompilation The key stored in the encrypted code makes data encryption meaningless; 2. When using a symmetric encryption algorithm, the same key is used for encryption and decryption, and the key is easily leaked, making data transmission less secure; 3. 1. When...
