Embodiment Construction

[0037] figure 1 is a structural block diagram of a security gateway device according to an embodiment of the present invention. Such as figure 1 As shown, the present invention provides a security gateway device 100 for a vehicle, which may generally include a microcontroller 10 (MCU) and an encryption chip 20 . The microcontroller 10 stores partial codes of the complete program of the security gateway device 100 . The encryption chip 20 stores the rest of the code together with the partial code to form the complete program, so that when an external module accesses the security gateway device 100 , it needs to be authorized by the encryption chip 20 to read the complete program.

[0038] The encryption chip 20 refers to a type of security chip that integrates various symmetric and asymmetric algorithms inside, has a very high level of security, and can protect internally stored keys and information data from being illegally read and tampered with.

[0039] The security gate...

Abstract

The invention provides a secure gateway device of a vehicle and a secure communication method, and belongs to the field of secure communication. The secure gateway device includes: a microcontroller storing a partial code of a complete program of the secure gateway device, and an encryption chip which stores residual codes which form the complete program together with the partial codes, so that anexternal module needs to be authorized by the encryption chip to read the complete program when accessing the secure gateway device. The invention also provides a secure communication method appliedto the secure gateway device. According to the secure gateway device and the secure communication method, the communication security of the gateway of the vehicle can be improved.

Description

technical field [0001] The invention relates to the field of safety communication, in particular to a vehicle safety gateway device and a safety communication method. Background technique [0002] In recent years, the popularity of Internet car manufacturing has increased greatly. With the addition of Internet companies, the degree of intelligence of cars has been greatly improved. For OEMs, the iteration of vehicle functions has become more frequent. The traditional 4S store 4S store or some designated places, and the need to use professional personnel and professional equipment to realize the flashing of the ECU side is no longer applicable, which not only consumes the manpower and material resources of the OEM, but also causes harm to consumers. Inconvenient, so many OEMs have developed remote flashing functions. Through OTA technology, connected car users only need to operate on their own car screen or mobile phone to realize the upgrade of related systems, which can sa...
