Problems solved by technology

[0003] In the application process of existing data transmission, although the broadband link transmission rate is faster and the cost is lower, the transmission security of the existing broadband link is low, because the data transmission of the broadband link is usually through asymmetric encryption The encrypted data is encrypted with the key authorized by the algorithm or the certificate. This encryption method has a wide range of applications and high universality. Even if the data is encrypted and then transmitted, it is easy to decipher the encrypted information.
Therefore, when users need to ensure highly secure data transmission, they usually use a dedicated wireless network for data transmission, but this transmission method is billed through the data transmission flow, which will cause high costs in the face of large data transmission.
It can be seen that the existing data transmission methods can no longer meet the user's needs for high security performance and low cost

Abstract

The invention provides a secure data transmission method, a terminal and a multi-mode communication terminal. The method comprises the following steps that: enabling a first terminal to encrypt data information to be transmitted; establishing a broadband communication link with the second terminal; transmitting the encrypted data information to the second terminal through the broadband communication link; obtaining preset key information related to the data information to be transmitted, wherein the preset key information can be used for decrypting the encrypted data information; establishinga narrowband communication link with the second terminal; and transmitting the preset key information to the second terminal through the narrowband communication link. According to the invention, thepurposes of improving the data transmission safety performance and reducing the data transmission cost are achieved.

Description

technical field [0001] The present invention relates to the technical field of encryption, and more specifically, relates to a method for safely transmitting data, a terminal and a multi-mode communication terminal. Background technique [0002] With the popularization and development of Internet technology, we have entered the era of big data. Both the efficiency and security of data transmission have received extensive attention. At present, there are usually two ways of data transmission, one is to transmit data through a broadband link, and the other is to transmit data through a dedicated wireless network. [0003] In the application process of existing data transmission, although the broadband link transmission rate is faster and the cost is lower, the transmission security of the existing broadband link is low, because the data transmission of the broadband link is usually through asymmetric encryption The encrypted data is encrypted using an algorithm or a key auth...
