The invention discloses a heterogeneous multi-core system, a vehicle-mounted application operation method, computer equipment and a computer readable storage medium, the heterogeneous multi-core system comprises a plurality of processors, at least one processor is provided with a high computing power system, and at least another processor is provided with a low computing power system. A mathematics arithmetic unit service module is deployed on the high computing power system, mathematics arithmetic unit services are published through a service oriented architecture (SOA), and the mathematics arithmetic unit services comprise a basic mathematics arithmetic service and an enhanced mathematics arithmetic service; and the low computing power system subscribes to the mathematics arithmetic unit service through a service oriented architecture (SOA). Through the computing power deployment, if the application deployed in the low computing power system has a high computing requirement, a plurality of applications do not need to be specially added and deployed on the high computing power system, so that the development workload is greatly reduced; and there is no need to deploy applications and construct inter-core communication protocols in high and low computing power systems, thereby simplifying the software architecture.

The invention relates to the technical field of automobile micro-service architectures, and discloses a three-layer forward service architecture based on a micro-kernel Hypervisor, which constructs a three-layer SOA architecture based on the micro-kernel Hypervisor, particularly provides a uniform interface and protocol for cross-virtual-machine service calling by using an SOAL2 logic bus, and improves the service performance of the micro-kernel Hypervisor, so that the service performance of the micro-kernel Hypervisor is improved, and the service performance of the micro-kernel Hypervisor is improved. Bus communication depends on bottom-layer security support of a microkernel Hypervisor, and services of different domains can be freely combined and cooperatively work on the premise of ensuring traffic safety, so that the technical problem that SOA (Service Oriented Architecture) cannot be fully coordinated in a virtualized environment is thoroughly solved, and the service security of the SOA in the virtualized environment is improved. And the function integration capability and the response real-time performance of the system are improved.

A method for a secure in-vehicle service oriented architecture with a MAC Generate Allow List includes receiving, at a secure environment, a request to transmit a message from a device. The request to transmit includes a request for a message authentication code. The method also includes determining, based on the request to transmit, an identity of the device, and determining, based on a message authentication generate allow list, that the request to transmit does not exceed a permission level of the device. Here, the permission level of the device is stored in the message authentication generate allow list. The method also includes obtaining a secure environment key assigned to the device, the secure environment key only accessible by the secure environment, and generating the message authentication code using the secure environment key assigned to the device.

The invention discloses a data communication method and system for a vehicle-mounted SOA architecture, and the method comprises the steps: generating second data based on to-be-communicated first data through a data providing unit; the data providing unit is a third-party service unit authorized and authenticated by the vehicle-mounted system; the second data comprises the first data and label data corresponding to the first data; the label data is used for indicating the credibility of the first data generated by the data providing unit; sending the second data to the vehicle-mounted central gateway through the data providing unit; the vehicle-mounted central gateway is configured to provide an operation environment of the security sandbox; distributing the second data to the data consumption unit through the vehicle-mounted central gateway; and verifying the credibility of the first data based on the tag data through the data consumption unit, and determining a security verification result for the first data. According to the scheme, hostile attacks and data cheating between the internal service / component units can be effectively prevented, and the authenticity and reliability of communication between the services are ensured.

A vehicle communication network with a service oriented architecture (SOA) includes a primary computing device designated for device authorization operations, a zone computing device in signal communication with the primary computing device via the communication network, and a plurality of edge devices in signal communication with the zone computing device and / or the primary computing device via the communication network. The primary computing device is configured to perform device authorization operations, including, receive broadcasted IDs from each of the edge devices, build / update a manifest of the plurality of edge devices based on the broadcasted IDs, reference the manifest and a list of authorized devices that are authorized to operate on the vehicle communication network, to thereby identify one or more unauthorized devices on the vehicle communication network, and prevent operation of the one or more unauthorized devices.
