Abstract

The invention provides a wireless communication module and a data communication system and an enciphered data remote transmission method. The wireless communication module comprises a coding unit, a transmitting unit, a receiving unit and a decoding unit. The coding unit is used for coding a to-be-encrypted data and packing the to-be-encrypted data into a data package. The transmitting unit is used for transmitting the data package coded by the coding unit to the outside through an Ecall voice channel. The receiving unit is used for receiving the data package from the outside through the Ecall voice channel. The decoding unit is used for decoding the data package received by the receiving unit. According to the data communication system and the enciphered data remote transmission method, an Ecall function of the wireless communication module is utilized, and therefore data in a certain amount can be transmitted in the voice channel, crack is difficult, besides, data are transmitted through the voice channel, eavesdrop is difficult, and therefore safety of the enciphered data remote transmission is improved.

Description

technical field

[0001] The present invention relates to a method for remote transmission of encrypted data, in particular to a wireless communication module, a data communication system including a plurality of wireless communication modules and a remote transmission of encrypted data realized by two wireless communication modules Methods. Background technique

[0002] The traditional encrypted data is transmitted by means of dual-tone multi-frequency, etc., but only a few fixed keys are used for dual-tone multi-frequency transmission, and the audio width of each key is almost the same and is universal, which leads to a problem in the sound When the frequency is certain, it is easy to be cracked, which greatly reduces the security of remote encrypted data transmission. Contents of the invention

[0003] The technical problem to be solved by the present invention is to overcome the defect that the encrypted data is easily cracked and the security is very low in the prior a...
