Problems solved by technology

The above method of key transmission and encryption algorithm takes a lot of time. A complete encryption algorithm takes seconds, which is far from meeting the requirements of real-time encryption. Moreover, the commonly used 128-bit key is too short and needs to be reused many times, affecting encrypted security

Embodiment Construction

[0012] like figure 1 As shown in the figure, to integrate the "quantum security module" with the functions of quantum random number generation and storage with the on-board computer, it can be directly integrated on a circuit board or connected by an external high-speed communication interface (such as USB3. 0). When the on-board computer leaves the factory, the quantum random number chip in the "quantum security module" generates enough quantum keys and distributes them locally with the cloud server. The key memory in the "quantum security module" is equally allocated two storage spaces, one half is used to store the distributed quantum key, and the other half is reserved for the new quantum key generated by the quantum random number chip.

[0013] like figure 2 As shown in the figure, during the driving process of the vehicle, the high-definition data obtained by the on-board camera is sent to the central processing unit of the on-board computer through the cache, and the...

Abstract

The invention discloses a high-speed encryption device and method using a true random number, a continuous random number is generated through a true random number chip, and the random number can be used as a secret key to encrypt a plaintext in any length. Through the simplest one-to-one XNOR or XOR operation between bits, the picture can be encrypted at the speed of more than 1GB / s (reaching the order of magnitude of the dominant frequency of the single-core CPU), and meanwhile, the safety is ensured. According to the invention, the efficiency and security of the encryption technology are improved, and the encryption problem of the Internet of Vehicles, especially in automatic driving, is solved.

Description

technical field [0001] The invention relates to a quantum random number high-speed encryption device and an encryption method for the Internet of Vehicles, especially for the encryption of large-capacity data in the process of automatic driving. Background technique [0002] The Internet of Vehicles is a prerequisite for the realization of autonomous driving technologies above the L3 level. Since traditional satellite positioning such as GPS cannot meet the vehicle positioning under high-speed conditions, it is necessary to introduce high-speed image acquisition technology for precise positioning and real-time road condition acquisition, and upload the collected image information to the cloud high-performance computer for processing in real time. During this process, the image collector may transmit some sensitive information related to the security of land and resources or personal privacy in the wireless network, which may lead to the leakage of the above-mentioned sensiti...
