The invention discloses an information transmission system which comprises an information exchange center, a first user device and a second user device. The information security hardware module is installed in the first user device, the information security hardware module is used for generating a first secret key establishment combination at least comprising a first public key-private key pair, and a first private key in the first public key-private key pair is stored in the information security hardware module. A first public key in the first public key-private key pair is transmitted to the information exchange center. The second user device is used for generating a shared key, encrypting a first information plaintext by using the shared key to obtain a first information ciphertext, transmitting the first information ciphertext to the information exchange center and then transmitting the first information ciphertext to the first user device, and the first user device is used for obtaining the shared key, decrypting the first information ciphertext by using the shared key and transmitting the decrypted first information ciphertext to the second user device. And obtaining the first information plaintext. According to the scheme, the effect of eliminating information security vulnerabilities can be achieved.
Description
technical field [0001] The invention relates to the field of information transmission, in particular to an information transmission system, a user device and an information security hardware module. Background technique [0002] With the continuous development of mobile communication systems, the bandwidth of data transmission has increased significantly, and users have almost switched to instant communication software for voice chat and transmission of text information and picture data. However, based on the structure of the current mainstream real-time communication software, it can be seen that the text information and picture data transmitted by users must be forwarded through an information exchange center, and the backup of the text information and picture data will be stored in the operator's settings. data server for some time or even not deleted at all. [0003] With the extensive use of real-time communication software by users and high requirements for informatio...
