Abstract

The invention discloses an information security protection circuit, a chip, a robot and a method, and the information security protection circuit enables address spaces of a general operation system and a special operation system to be mutually independent through two independent memory banks, and a sensor which generates sensitive information is physically isolated from a general processor. An attacker cannot directly access the sensitive information by using the general processor, so that the security of the sensitive information in the robot is greatly improved; meanwhile, an MIPI bus in an SOC (System On Chip) is adopted as a communication means between the general processor and the special processor, and the bus is not exposed, so that an attacker cannot capture data on the bus, and the security of sensitive information is further improved.

Description

technical field [0001] The invention relates to the field of information security, in particular to an information security protection circuit, chip, robot and method. Background technique [0002] A large amount of valuable and sensitive information is stored in the robot, such as camera data or lidar data, making it a target for attackers, resulting in memory data leakage accidents from time to time. With the popularity of robot products in the market, the number of robots is constantly expanding, and the demand for information security of robots is becoming increasingly strong. Contents of the invention [0003] In order to solve the above problems, the present invention provides an information security protection circuit, chip, robot and method, which greatly improves the security of sensitive information in the robot. Concrete technical scheme of the present invention is as follows: [0004] An information security protection circuit, the circuit includes a general-...
