Embodiment Construction

[0047] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is said to be "fixed" to another element, it may be directly on the other element, or there may be one or more intervening elements therebetween. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or one or more intervening elements may be present therebetween. The orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", and "bottom" used in this specification is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the The invention and the simplified description do not indicate or imply that the device or element referred to must have a specific orientation...

Abstract

The invention relates to a vehicle communication interface device and an authentication method thereof. The vehicle communication interface device executes the following steps: determining at least one authentication element related to a to-be-executed function in the vehicle communication interface device, and uploading the at least one authentication element to a server; calculating, according to the authentication element, to obtain a corresponding first authentication value; receiving a second authentication value obtained by calculation according to the authentication element through theserver; determining whether the first authentication value and the second authentication value match; if so, determining that the vehicle communication interface device is successfully authenticated,performing the to-be-executed function; and if not, determining that the authentication of the vehicle communication interface device fails. The authentication method is completed by using a server located on the network side, with no need to add additional hardware chips to the hardware, which is advantageous for reducing product cost. Moreover, the server on the network side has no limitation onbuilt-in hardware chips, and can have powerful performance so that the authentication method can be extended to obtain good flexibility and higher security.

Description

【Technical field】 [0001] The invention relates to the technical field of automobile diagnosis products, in particular to an automobile communication interface device and an authentication method thereof. 【Background technique】 [0002] Before an automotive diagnostic product performs a certain function (such as establishing a communication connection with an automotive control system), it usually needs to authenticate the automotive communication interface device to ensure that the function can be executed smoothly. This device authentication process is usually done using a dedicated chip built into the automotive communication interface device. [0003] As a part of the hardware circuit, the dedicated chip is usually packaged and fixed in the device before the product leaves the factory. This makes extensions or changes to dedicated chips nearly impossible. Moreover, limited by the cost of hardware, dedicated chips usually have very limited storage space. [0004] These ...
