The invention discloses a safe and quick starting method for a vehicle-mounted terminal and a computer readable storage medium, and the method comprises the steps: obtaining software data and a preset symmetric key when the vehicle-mounted terminal is started; segmenting the software data according to a preset first byte number to obtain at least one segment of second segment data, and respectively obtaining the second segment data from the first segment data according to a preset value position and a preset second byte number; splicing the second segment data, and encrypting the spliced data according to the symmetric key to obtain a to-be-verified encryption value corresponding to the software data; and if the encryption value to be verified is consistent with an authentication encryption value corresponding to the software data pre-stored in the vehicle-mounted terminal, starting the vehicle-mounted terminal. According to the method, the integrity and authenticity of the software can be ensured, and the safe starting speed can be increased.
本发明公开了一种车载终端的安全快速启动方法及计算机可读存储介质,方法包括:当启动车载终端时,获取软件数据以及预设的对称密钥;根据预设的第一字节数,对所述软件数据进行分段,得到至少一段的第二分段数据,并根据预设的取值位置以及预设的第二字节数,分别从各第一分段数据中获取第二分段数据;将各第二分段数据进行拼接,并根据所述对称密钥对拼接后的数据进行加密,得到所述软件数据对应的待验证加密值;若所述待验证加密值与车载终端中预存的所述软件数据对应的认证加密值一致,则启动车载终端。本发明可保证软件的完整性和真实性,且可提高安全启动的速度。
