According to the automobile information security integrity verification system based on the white-box cryptographic algorithm, a secure boot module is adopted as a tool for automobile information security integrity verification, and the secure boot module comprises a Control Logic sub-module, an SW Crypto sub-module, a WbKey sub-module and a Stored Encrypted APP CRC32Value sub-module; the application process of the automobile information safety integrity checking system comprises three steps of safety starting, white box secret key generation and white box library generation. Under the action of related processes, a decrypted secret key is hidden in software in a pure software mode, meanwhile, decryption work can be normally carried out, even if an attacker completely masters an operation platform, the attacker cannot obtain a password, safety is greatly improved, on the premise that certain system safety is guaranteed, the cost of hardware HSM is saved, and the safety of the system is improved. The method ha
