Abstract

The application discloses data transmitting and receiving methods and devices. One specific embodiment of the data transmitting method comprises the following steps: transmitting data to be transmitted; randomly generating an encryption length; encrypting the data from a predetermined position till an encryption length reaches the abovementioned encryption length in order to generated encrypted data; generating message header information including the encryption length; and constructing the message header information and the encrypted data into a complete message for transmission. Through the embodiment, the problem of high CPU (Central Processing Unit) occupation rate of a data transmission end is solved. One embodiment of the data receiving method comprises the following steps: acquiring received data; reading the message header information in the data, and extracting a decryption length; and decrypting the data from a predetermined position till a decryption length reaches the abovementioned decryption length in order to generate decrypted data. Through the embodiment, the problem of high CPU occupation rate of a data receiving end is solved.

Description

technical field [0001] The present application relates to the field of computer technology, specifically to the field of Internet technology, and in particular to a data transmission and reception method and a transmission and reception device. Background technique [0002] With the rapid development of the Internet, the amount of data transmission is also increasing, and the requirements for the speed and security of data transmission are also getting higher and higher. For security issues, it is mainly solved by encrypting data. At present, most of data encryption adopts full message encryption. However, because the full message encryption needs to encrypt and decrypt all messages, the CPU (Central Processing Unit, central processing unit) occupancy rate of the transmitting end and the receiving end is high. Contents of the invention [0003] The purpose of this application is to propose an improved data transmission method and data transmission device to solve the tec...
