A vehicle data upgrading protection method, a system, and a vehicle. The method comprises an encryption link, a decryption link, and an intermediate data conversion link; the encryption link is mainly used for encrypting data so as to generate an encrypted data upgrade package; the intermediate data conversion link is used for performing conversion processing so as to generate an intermediate decryption data upgrade package; and the decryption link is mainly used for decrypting the intermediate data upgrade package so as to generate a decrypted data upgrade package. The encryption link comprises a compression step, a first operation step, a data merging step, a signature step, and a packaging step. According to the method, data encryption is achieved by means of software, the requirements for hardware are reduced, and costs are saved. Multi-layer verification is performed on the data, so that the security of the data is effectively ensured. Due to multi-layer encryption, the difficulty of tampering the data by hackers is increased, and the data is better protected.
