Embodiment Construction

[0031] Embodiments of the present invention provide a method and device for data transmission. The sending end of the method generates a random number m, and converts the ASCII value of each character in the data to be sent into an m-ary number with a specified number of digits, and obtains the encrypted The data to be sent, and then send the random number m and the encrypted data to be sent to the receiving end. Because in the embodiment of the present invention, when the sending end encrypts the data to be sent each time, it converts the ASCII value of each character in the data to be sent into a random m-ary number, therefore, even when sending the same multiple data to be sent At the same time, the results obtained after encrypting the multiple data to be sent are also different, thereby effectively reducing the risk of the encryption algorithm being cracked and improving the security of data transmission.

Abstract

The invention discloses a method and a device of data transmission. The method and the device of data transmission are used for solving the problem that in the prior art safety of the data transmission is low. With the method, a sending end produces a random number m, and an American standard code for information interchange (ASCII) value of each character in data needed sending is changed into an m system number with an appointed bit, and then encrypted data needed sending are obtained. The random number m and the encrypted data needed sending are sent to a receiving end. Due to the fact that when a sending end encrypts the data needed sending every time, each ASCII value of each character is converted into a random m system number, results of a plurality of data needed sending and obtained after encryption are different even the same plurality of data needed sending are sent. Therefore, the risk of an encryption algorithm to be cracked is effectively reduced and security of data transmission is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission method and device. Background technique [0002] At present, in order to ensure the security of data transmission, when the sending end sends data to the receiving end, the data usually needs to be encrypted for transmission. [0003] In the prior art, the sending end encrypts and transmits the data to be sent as follows: for each character in the data to be sent, convert the character into an encrypted string according to the specified conversion rules, and convert each character The resulting encrypted strings are combined to obtain the encrypted data to be sent, and then the encrypted data to be sent is sent to the receiving end. When the receiving end receives the encrypted data, it decrypts according to the reverse process of the above encryption process to obtain the original data. [0004] However, in the prior art, when the sending end...
