Abstract

The invention provides a method and a system for activating a vehicle-mounted terminal for the first time after factory setting is restored, belonging to the technical field of vehicle-mounted software; and performing resource acquisition tasks in sequence to acquire a certificate ready event state, wherein the resource acquisition tasks comprise certificate loading, key loading, token acquisition and configuration table pulling, and acquiring a two-dimensional code for activating the vehicle-mounted terminal when the network available event state is network available and the certificate ready event state is certificate ready. The invention converts parallel risks into controllable serial, is convenient for system maintenance and problem investigation, greatly reduces average code output time of first startup, improves user experience, supports idempotent caching, can reduce code output time of second startup, improves system response speed, automatically waits for network readiness, avoids invalid retry caused by network late arrival, reduces invalid request to cloud, reduces cloud pressure and improves overall stability.

Description

Method and system for first activation of vehicle-mounted terminal after factory setting recovery Technical Field The invention relates to the technical field of vehicle-mounted software, in particular to a method and a system for activating a vehicle-mounted terminal for the first time after factory setting is restored. Background After the automobile engine is restored to factory setting, the system needs to reload a plurality of key resources such as equipment certificates, equipment keys, cloud token, configuration tables and the like from the security partition, and is limited by factors such as eMMC reading and writing, HSM checking, network RTT and the like, and 20s-60s are needed for first startup. Existing schemes typically employ parallel calls or simple retries, but suffer from the following drawbacks: the parallel call causes multithreading to access unfinished safe storage at the same time, and the problems of empty certificate/key, token authentication failure, interface error reporting and the like occur; A single simple retry cannot distinguish the cause of failure when no network or certificate is not ready, the user experience is poor, and the avalanche request may be triggered by frequent user clicks. Disclosure of Invention The invention aims to solve at least one of the problems in the prior art, and provides an integrated solution capable of serializing key resource loading, independently retrying according to stages, network monitoring self-adaptive refreshing and global abnormal bottom.
