Abstract

The application discloses an automobile data diagnosis method and device. The method comprises the following steps: receiving an access request that is sent by diagnosis equipment and comprises a first digital digest obtained by performing hash operation on to-be-processed data, a joint serial number and an equipment ID of the diagnosis equipment, the joint serial number and the to-be-processed data including vehicle data and indication information for indicating at least one request algorithm; judging whether the equipment ID is legal or not according to the access request; judging whether the access request conforms to a preset strategy or not under the condition that the equipment ID is judged to be legal; processing the vehicle data by using at least one request algorithm to obtain a diagnosis result under the condition of judging that the access request conforms to the preset strategy; and sending the diagnosis result to the diagnosis equipment. According to the invention, the algorithm for diagnosing the automobile data can be prevented from being maliciously cracked and illegally used, and the safety diagnosis of the automobile data is realized.

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 ...
