[0003] At present, when downloading the OTA upgrade package of the ECU, it is usually directly connected to the vehicle end through the TSP platform, and the OTA upgrade package download is realized through the long connection service channel established between the TSP server and the vehicle end. The download process not only affects the data transmission at the TSP end, but also affects the overall download rate of the upgrade package; in addition, when multiple vehicles in different regions download the upgrade package at the same time, network congestion is prone to occur and the response speed of the server will be reduced , which makes the download efficiency low, which also causes a bad upgrade experience

The invention discloses an OTA upgrade package downloading method and device, a vehicle end and a server, and belongs to the technical field of space downloading. The method comprises the following steps: an OTA server receives a download request of an upgrade package sent by a vehicle end; the OTA server determines a CDN server corresponding to the download request and sends a link address of theCDN server to the vehicle end, wherein the CDN server stores a ciphertext upgrade package of the upgrade package and signature information obtained by signing the ciphertext upgrade package through an OTA private key; the vehicle end downloads the ciphertext upgrade package and the signature information from the CDN server according to the link address of the CDN server; the vehicle end uses a pre-acquired OTA public key to verify the signature information, and requests a key for decrypting the ciphertext upgrade package from the OTA server if the signature verification is passed; and the vehicle side decrypts the ciphertext upgrade package by using the key returned by the OTA server to obtain the upgrade package. According to the embodiment of the invention, the overall downloading rateof the OTA upgrade package can be increased.
Description
technical field [0001] The present invention relates to the technical field of space downloading, in particular to an OTA upgrade package downloading method, device, vehicle terminal and server. Background technique [0002] OTA (Over-the-Air) technology is a technology for remote management of data and applications through the air interface of mobile communication, and is widely used in downloading and upgrading services. For example, a car with OTA function can upgrade the car ECU (Electronic Control Unit, electronic control unit) online through the Internet to realize the optimization and upgrade of ECU performance. [0003] At present, when downloading the OTA upgrade package of the ECU, it is usually directly connected to the vehicle end through the TSP platform, and the OTA upgrade package download is realized through the long connection service channel established between the TSP server and the vehicle end. The download process not only affects the data transmission ...
