Abstract

The invention belongs to the field of communication, and discloses a gateway system based on safe communication, which comprises a plurality of gateways and a server, at least one first gateway is provided with a short message communication interface, the plurality of gateways are in safe communication with the server, the first gateway requests a secret key from the server through a short message, the server sends the secret key to the first gateway, and the server sends the secret key to the first gateway. The first gateway splits a secret key into a plurality of sub-secret keys according to a Shamir secret sharing threshold method and sends the sub-secret keys to other gateways, after data to be sent by other gateways are partitioned, the sub-secret keys are randomly used as symmetric secret keys to encrypt the partitioned data and send the partitioned data to the server, and the server decrypts the received data by using the sub-secret keys. The encrypted secret key is sent through the short message, it is effectively guaranteed that the secret key is not leaked, the secret key is further decomposed into the sub-secret keys, the sub-secret keys are used for encrypting data, and the encryption effect is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a gateway system based on safe communication. Background technique [0002] The core of communication security is to ensure the availability of services and to protect services and data from illegal use. A variety of means of sabotage, attack, and eavesdropping with the aim of undermining communication security. Security is a key link in the home LAN. Most home smart devices lack the ability to securely send end-to-end encrypted communications, and there is a problem of sending secret information such as account numbers in clear text, which may lead to malicious theft of sensitive information. Contents of the invention [0003] In view of this, the present invention proposes a gateway system based on secure communication, including a first gateway, multiple smart devices and a server, wherein the first gateway has a short message communication interface, and...
