Smart home secret communication system based on quantum true random number and control method

Abstract

The invention relates to a smart home secret communication system based on a quantum true random number and a control method. Same secret keys are stored in a storage medium of the mobile communication device and a storage medium of the smart home device, and the secret keys comprise quantum true random numbers. When mobile communication equipment accesses intelligent household equipment through a network, data sent to the intelligent household equipment through the network at least comprises an instruction encrypted by a secret key and a current pointer of the secret key, and when an encryption unit of the mobile communication equipment encrypts the instruction by using the secret key every time, used quantum true random numbers in the secret key are rejected; the pointer is updated to the position pointing to the unused quantum true random number, and a decryption unit of the intelligent home equipment decrypts the instruction according to the quantum true random number represented by the current pointer of the secret key and executes the instruction.

Description

technical field [0001] The invention mainly relates to the technical field of smart home, more specifically, to a smart home security communication system and control method based on quantum true random numbers that can ensure that the smart home is under safe conditions. Background technique [0002] In the current Internet era, the momentum of smart home is becoming more and more popular, and smart home has become one of the hottest topics in the current market. But at the same time, with the popularity of smart homes, security risks also arise. Smart home is based on Internet devices, but the Internet itself has many security risks. The combination with the Internet also makes smart home devices closer to security risks and easy to become the target of attacks. Smart home technology is becoming more and more advanced and complex, but it will also bring more security threats. For example, smart phones can unlock doors, turn on air conditioners, and access cameras. All kin...

Problems solved by technology

[0005] At present, the smart home systems on the market basically use a customized and simple version of the Linux system. First of all, the technology is not mature enough, and the developers have not paid enough attention to its security.

Trojan horses and viruses have turned countless computers and mobile phones into a network full of bots and zombies, and now the same risk is spreading to smart home devices, and insufficient defense capabilities of routers will become a big problem
