Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden on the person of ordinary skill in the art based on embodiments of the present invention, are intended to be within the scope of the present invention.
In The related art, in The process of upgrading The software in The automobile by adopting The Over The Air technology (OTA for short), specifically, on an electronic control unit (Electronic Control Unit for short ECU) which needs to upgrade The software, the upgrading configuration management main control module (Update and Configuration Management Master for short UCM Master) and The upgrading configuration management service module (Update and Configuration Management Server for short UCM Server) in The Over The Air service end can be mutually matched, and a built-in encryption module in The Over The Air service end is called to encrypt and decrypt The downloaded software package, and The process of upgrading The software of The automobile is finally realized. The existing over-the-air technology is implemented by upgrading an encryption module built in a configuration management module (Update and Configuration Management, abbreviated as UCM), and the specific implementation architecture is shown in fig. 1.
Fig. 1 is a schematic diagram of an existing architecture for implementing OTA security upgrade provided in an embodiment of the present invention, where an OTA client, that is, an over-the-air terminal, sends an upgrade request, and invokes an upgrade interface provided by a UCM to complete an upgrade operation. The UCM is used as an OTA Server, namely an over-the-air Server and is responsible for carrying out specific upgrading operation, wherein the UCM Master is responsible for controlling and managing vehicle upgrading, the UCM Server is used for completing operations such as encryption and digital signature of an upgrade package by relying on a built-in encryption module, and the UCM Server is matched with the UCM Master for upgrading, and the UCM Server is used for completing decryption and digital signature verification of the upgrade package by relying on the built-in encryption module.
However, in the existing OTA security upgrading implementation process, the UCM Master and the UCM Server both depend on an internal encryption module, so that the coupling is strong; in addition, the built-in encryption module cannot support encryption and decryption operations across the ECU; meanwhile, the flexibility of the built-in encryption module is poor when the function is expanded. These drawbacks all make the vehicle software upgrades less flexible.
In view of this, the application provides a vehicle software upgrading method, system, device, electronic equipment and storage medium, which encrypt and digitally sign an initial upgrade package through an external preset encryption module, so that dependence on an internal encryption module is avoided, flexibility in the process of expanding encryption functions is improved, and thus flexibility in upgrading vehicle software is also improved; in addition, as the preset encryption module is only arranged on one of the electronic control units, the software packages corresponding to other electronic control units can be encrypted and decrypted through the preset encryption module, so that the cross-domain encryption and decryption operation is realized, and the efficiency and the flexibility of upgrading the vehicle software are improved.
The terms "first" and "second" are used below for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the embodiments of the present disclosure, unless otherwise indicated, the meaning of "a plurality" is two or more. In addition, the use of "based on" or "according to" is intended to be open and inclusive in that a process, step, calculation, or other action "based on" or "according to" one or more of the stated conditions or values may in practice be based on additional conditions or beyond the stated values.
The vehicle software upgrading method provided by the application can be applied to computer equipment (electronic equipment), wherein the computer equipment can be a server or a terminal, the server can be one server or a server cluster consisting of a plurality of servers, the embodiment of the application is not particularly limited to the method, and the terminal can be but not limited to various personal computers, notebook computers, smart phones, tablet computers and portable wearable equipment.
Taking the example of a computer device being a server, FIG. 2 shows a block diagram of a server, as shown in FIG. 2, which may include a processor and memory connected by a system bus. Wherein the processor of the server is configured to provide computing and control capabilities. The memory of the server includes nonvolatile storage medium and internal memory. The nonvolatile storage medium stores an operating system, a computer program, and a database. The internal memory provides an environment for the operation of the operating system and computer programs in the non-volatile storage media. The computer program is executed by a processor to implement a vehicle software upgrade method.
It will be appreciated by those skilled in the art that the structure shown in fig. 2 is merely a block diagram of a portion of the structure associated with the present application and does not constitute a limitation of the server to which the present application is applied, and that alternatively the server may include more or less components than those shown, or may combine some components, or have a different arrangement of components.
The execution subject of the embodiment of the present application may be a computer device or a vehicle software upgrading device, and in the following method embodiment, the execution subject is described with reference to the computer device.
Fig. 3 is a flowchart of steps of a method for upgrading vehicle software according to an embodiment of the present invention. As shown in fig. 3, the method comprises the steps of:
step 302, acquiring initial upgrade packages corresponding to each upgrade request sent by the over-the-air terminal through the upgrade configuration management main control module, calling a preset encryption module to encrypt and digitally sign the initial upgrade packages for each initial upgrade package, and sending the processed first upgrade package to the corresponding upgrade configuration management service module.
The preset encryption module is deployed on any one target electronic control unit in the electronic control units. The upgrade request is used for upgrading the vehicle software, namely, upgrading the vehicle software of the electronic control unit with the upgrade requirement, and the over-the-air Server can comprise an upgrade configuration management main control module UCM Master and an upgrade configuration management service module UCM Server corresponding to each electronic control unit ECU.
When the vehicle software is required to be upgraded on each of the plurality of ECUs, upgrading requests respectively corresponding to the electronic control units can be sent to the over-the-air downloading server through the over-the-air downloading terminal. Optionally, the upgrade configuration management module UCM may serve as an over-the-air server, and the over-the-air terminal may send an upgrade request to the UCM. The upgrade request is usually initiated actively by a user, that is, the user can select which ECUs need to be upgraded by the over-the-air terminal, so that the over-the-air terminal sends upgrade requests corresponding to a plurality of electronic control units to the over-the-air server according to the selection operation of the user.
After sending the upgrade request to the UCM, an application program interface (Application Programming Interface, abbreviated as API) provided by the UCM may be called to read an initial upgrade package corresponding to each upgrade request from a designated storage path carried in the upgrade request, so that each initial upgrade package is obtained through the UCM Master.
After each initial upgrade package is obtained by the UCM Master, encryption and digital signature processing are required to be carried out on each initial upgrade package, and the security and the authenticity of the initial upgrade package can be ensured by carrying out encryption and digital signature processing on the initial upgrade package, so that data in the initial upgrade package is prevented from being stolen or maliciously tampered. Existing crypto modules are known to be implemented through a remote procedure call protocol framework (Remote Procedure Call, RPC for short) or Socket-based client/server architecture C/S framework. Fig. 4 is a schematic diagram of an existing implementation architecture of a crypto encryption module according to an embodiment of the present invention, an operation flow based on the implementation architecture of the crypto encryption module is shown in fig. 5, and fig. 5 is a schematic diagram of an operation flow of the existing crypto encryption module according to an embodiment of the present invention.
The cryptin client sequences the message requested by the OTA client through a serialization module of the cryptin IPC and sends the message to a cryptin server, and finally provides an accessible API for Service-oriented architecture (Service-Oriented Architecture, abbreviated as SOA) application, namely SOA application, the cryptin server receives the message request and performs specific implementation, and finally provides services to the outside. The cryptio client and the cryptio server are strongly dependent on the cryptio IPC module to complete communication operation, so that on one hand, the coupling is strong, the adopted TCP/UDP communication mode is not flexible enough in configuration, and on the other hand, encryption and decryption operation across the ECU cannot be supported.
Based on this, in the embodiment of the present application, for each initial upgrade package, the preset encryption module is invoked to encrypt and digitally sign the initial upgrade package, and optionally, the processed first upgrade package may be sent to the corresponding upgrade configuration management service module through the preset communication management module. The preset encryption module is deployed on any one target electronic control unit in the electronic control units.
In SOME alternative embodiments, the preset communication management module may be a com communication management module based on SOME/IP communication protocols.
Fig. 6 is a schematic diagram of an upgrade configuration management system architecture provided by an embodiment of the present invention, where in an automobile open system architecture (Automotive Open System Architecture, abbreviated as AutoSar) of an adaptive platform (Adaptive Platform, abbreviated as AP), a com communication management module provides a service-oriented communication method for an SOA application service and the adaptive platform, and implements binding of an SOME/IP communication protocol. The SOME/IP communication protocol is used as a base protocol of vehicle-mounted Ethernet communication, can proxy, forward and control SOME/IP messages of all Ethernet communication nodes, supports data cross-domain communication inside or among ECUs, supports encryption and authentication of data, and can ensure safe transmission of data.
The preset encryption module is a cryptand encryption module which uses SOME/IP to realize service-oriented cross-domain communication and supports encryption and decryption operations and the like across the ECU, and can use a serialization/deserialization operation method provided by SOME/IP and interfaces such as service registration, service discovery and service call to realize remote call, so that the cross-domain communication in the ECU or among the ECUs is finally completed, and flexible and efficient TCP/UDP communication mode configuration can be completed by directly configuring a com communication management module.
Fig. 7 is a schematic diagram of an OTA security upgrade service implementation architecture of a preset encryption module capable of crossing domains according to an embodiment of the present invention. Fig. 8 is a schematic diagram of a preset encryption module implementation architecture based on SOME/IP communication according to an embodiment of the present invention. The crypto client can discover the service through SOME/IP and use the service to provide corresponding API for SOA application. The crypto server can receive and process the message request of the crypto client through SOME/IP registration service and provide service to the outside. The SOME/IP communication protocol of the com communication management module provides for the implementation of remote procedure calls and message notifications, and supports serialization of messages, which can be used for data efficient communication inside or between ECUs. Therefore, the dependence of the existing crypto encryption module on the crypto IPC is eliminated, and the SOME/IP related interface provided by the com module is directly used for completing the operations such as safe and efficient communication, serialization and the like between the crypto client and the crypto server.
Further, as shown in fig. 9, fig. 9 is a schematic diagram of an implementation flow of a preset encryption module operation based on SOME/IP communication according to an embodiment of the present invention. The SOME/IP server end completes service registration bound by a specific communication protocol through providing service (OfferService), and provides service. The SOME/IP client completes the search of the service through the discovery service (StartFindService). When the SOA application service calls the API, the cryptio server and the cryptio client can complete serialization/deserialization of the message and remote Call of the Method only by performing Method Call service Call (Request/Response).
In SOME alternative embodiments, the process of SOME/IP-based cross-domain communication is described using two SOA application services on different ECUs as an example. Fig. 10 is a schematic diagram of cross-domain communication performed by two SOA application services on different ECUs according to an embodiment of the present invention, as shown in fig. 10.
The SOA application service 1 in the ECU1 invokes an AUTOSAR (AUTOSAR Runtime for Adaptive applications, abbreviated as ARA) crypto encryption module of the AP adaptive application, that is, an API such as encryption and decryption of a preset encryption module, to send data to the ECU2, where the crypto encryption module performs Serialization method invocation and parameter entry by invoking Serialization of the SOME/IP communication protocol in the com communication management module, so as to perform Serialization processing on the obtained data, generate a serialized message, and thus return the serialized message to the crypto encryption module, where the crypto encryption module then transmits the obtained serialized message to the com communication management module, where the com communication management module transmits the obtained serialized message to the ECU2 through SOME/IP communication.
After receiving the above-mentioned serialization message, the com communication management module in the ECU2 sends the above-mentioned serialization message to the cryptio encryption module, and the cryptio encryption module calls the Deserialization of the SOME/IP communication protocol in the com communication management module to make Deserialization method call and enter into the parameters so as to make Deserialization treatment on the above-mentioned serialization message, and then returns the Deserialization message to the cryptio encryption module, and the cryptio encryption module transfers the above-mentioned Deserialization message to the SOA application service 2 in the ECU2, so that the SOA application interaction across the ECU can be finally completed.
It should be noted that, in the process of performing cross-domain communication by using two SOA application services shown in fig. 10, preset encryption modules are deployed on both ECUs, and fig. 10 is merely an exemplary illustration of a process of performing cross-domain communication based on SOME/IP. In the embodiment of the application, when the preset encryption module is called to encrypt and digitally sign the initial upgrade package, the preset encryption module can be only deployed on any one target electronic control unit in the electronic control units. After each initial upgrade package is encrypted and digitally signed, the first upgrade package after processing can be transmitted to UCM servers corresponding to other ECUs through SOME/IP communication by the com communication management module.
In the embodiment, the implementation of remote procedure call and message notification is provided through the SOME/IP communication protocol of the com communication management module, and the serialization of the message is supported, so that the method can be used for data efficient communication in the ECU or among ECUs, thereby eliminating the dependence of the existing crypto encryption module on the crypto IPC, and the operations such as safe and efficient communication and serialization between the crypto client and the crypto server are completed directly by using the SOME/IP related interface provided by the com module; in addition, the preset encryption module can be only deployed on any one target electronic control unit in each electronic control unit, so that the resource occupation in the electronic control unit can be saved, the function of the preset encryption module can be maintained conveniently in the later period, and the safety and reliability of the vehicle software upgrading are improved.
In other alternative embodiments, when the UCM Master invokes the preset encryption module to encrypt and digitally sign the initial upgrade package, as shown in fig. 11, fig. 11 is a flowchart of the encryption and digital signature process provided in the embodiment of the present invention, where the flowchart includes:
step 1102, obtaining a combined encryption algorithm preconfigured by a user.
And 1104, calling a preset encryption module to encrypt and digitally sign the initial upgrade package based on a combined encryption algorithm.
The combined encryption algorithm may include multiple encryption algorithms determined based on the data attribute information of the initial upgrade package, where the data attribute information may be data type information, data size information, and the like, and of course may also be other types of data attribute information, which is not specifically limited in the embodiment of the present application.
