Description

Method, device, equipment, medium and program product for configuring end-to-end software Technical Field The present application relates to the field of automotive electronics, and in particular, to a method, an apparatus, a device, a medium, and a program product for configuring end-to-end software. Background In recent years, with the development of software-defined automobiles, intelligent automobile software architecture is being upgraded toward SOA (Service-Oriented Architecture, service-oriented distributed architecture). The sub-functions of the whole vehicle system are disassembled in a service mode, and the processes of version iteration, code updating and the like of the ECU are more flexible. For this highly software-implemented new architecture, it is particularly important how to ensure the integrity and reliability of the communication data when it comes to the transmission of important data between the vehicle interiors or between the external ECUs. E2E (End-to-End Protection) Protection is used as a basic component in the AUTOSAR architecture, following a layering principle, to protect inter-component data communication through standardized interfaces. In the related art, according to the interface function under the AUTOSAR standard and the related definition of E2E Profile, the reverse verification of the protected data transfer function and CRC (Cyclic Redundancy Check) between SWC (Software Component) is performed by using a conventional handwriting code, and OEM (Original Equipment Manufacturer) puts forward constraints on the communication protected data arrangement and E2E (End-to-End) algorithm. However, when API (Application Programming Interface) of E2E protection is needed among carding ECUs in the related technology, the use of E2E protection of the same interface among ECUs and even among different SWCs of the same ECU is inconsistent, so that an E2EPW _Read interface function needed to implement E2E protection is accurately defined through handwriting codes for an application layer and a bottom layer decoupling architecture of an SOA, the application layer can be matched with the application layer without error to use, the development of early carding and integration processes is relatively candelable, and the implementation effect of the SOA architecture is not ideal. Secondly, when the protected API test is performed to verify whether the end-to-end communication has problems, depending on different projects, the E2E Profile also has a certain difference or more E2E algorithm, and the correctness and universality of the data Header are poor through the conventional codes (CRC-8, CRC-16, CRC-32 and the like) to be solved. Disclosure of Invention The application provides a configuration method, a device, equipment, a medium and a program product of end-to-end software, which are used for solving the problems of complicated configuration, error-prone code manual integration, non-intuitive function verification, low efficiency and the like in the traditional E2E protection implementation.
