Background
The vehicle-mounted intelligent terminal is called a T-Box (telematics Box) and is used as a control unit for vehicle body networking, vehicle related information including but not limited to position information, attitude information and vehicle state information is acquired by connecting a CAN bus on a vehicle, the information is transmitted to a cloud control background through a self-contained wireless communication module, a vehicle legal user enters the cloud control background by using a mobile phone APP and a webpage client, and corresponding remote operation is carried out on the vehicle by issuing data and instructions. With the increasing of the degree of vehicle intelligence, the information capacity of vehicle interaction with the outside is increased rapidly, and the existing method cannot meet the requirements of high safety and high reliability of intelligent networked automobile data and content services.
In the aspect of protecting the data self-security, an encryption technology is generally adopted for solving the problem, and the method can be divided into an asymmetric password and a symmetric password according to a secret key mode. The security of the asymmetric password, namely the public and private key password depends on the computational complexity of the mathematical difficulty problem which the public key algorithm depends on, and is threatened by increasing the mathematical level and the computing power; the symmetric cipher refers to a cipher with the same encryption key and decryption key, the security of the symmetric cipher depends on the security of the encryption key and the security of the encryption and decryption algorithm, the randomness of the encryption key is poor, and the security is greatly reduced due to the long-term use of the same group of encryption keys and the insufficient protection measures taken for updating the encryption key. Under the condition that the key length is the same as other conditions, the symmetric cipher occupies less CPU than the asymmetric cipher, the network consumption is low, and the encryption and decryption speed is high.
The random number used in encryption can be extracted from classical physical noise such as thermal noise and electrical noise, and a pseudo-random number can be generated by means of computer simulation. In principle, classical physical processes can be modeled taking into account all variables, but the randomness produced by quantum physical processes can be truly random. The use of quantum random numbers in encryption can improve security.
