Abstract

The present application discloses a method and device for car data diagnosis. The method includes: receiving an access request sent by a diagnostic device. The access request includes a first digital abstract, a joint serial number and data to be processed, wherein the data to be processed includes vehicle data and Indication information used to indicate at least one request algorithm, the first digital digest is obtained by hashing the data to be processed, the serial number of the connector, and the device ID of the diagnostic device; judging whether the device ID is legal according to the access request; judging the device ID If it is legal, judge whether the access request conforms to the preset policy; if it judges that the access request conforms to the preset policy, use at least one request algorithm to process the vehicle data to obtain a diagnosis result; and send the diagnosis result to the diagnosis device. The application can prevent the algorithm used for diagnosing the automobile data from being maliciously cracked and illegally used, and realizes the safety diagnosis of the automobile data.

Description

technical field [0001] The present application relates to the field of information security, in particular to a method and device for automobile data diagnosis. Background technique [0002] Automobile algorithm is the core technology for automobile diagnostic equipment to diagnose various data of automobiles. Automobile algorithms are often used to perform given calculations on vehicle data read by diagnostic equipment from the OBD (On Board Diagnostics) interface of the vehicle, thereby converting them into data displayed on the diagnostic equipment. [0003] At present, the automobile algorithm for decoding the read vehicle data is compiled into an algorithm dynamic library and stored in the diagnostic software of the diagnostic equipment. Once the vehicle data is read, the algorithm dynamic library directly performs corresponding operations on the vehicle data according to the corresponding request. operate. The algorithm dynamic library is not only easy to be cracked ...
