White-box-based in-vehicle infotainment terminal software encryption and decryption method and device

The invention discloses a white-box-based vehicle terminal software encryption and decryption method and device, and relates to the completely unmanned driving field and the auxiliary driving field, to-be-encrypted data can be firstly obtained, the to-be-encrypted data is used for data transmission in intelligent driving, the to-be-encrypted data is encrypted through a preset encryption algorithm, and ciphertext data is obtained. And then the ciphertext data can be sent to a set device, so that the set device decrypts the ciphertext data according to each sub-key to obtain decrypted data, each sub-key performs operation on a pre-generated decryption key through a preset decomposition operation mode, and after each sub-key is generated, the decryption key is deleted, so that the risk that other people acquire the original decryption key can be avoided, and the data security is ensured. 本说明书公开了一种基于白盒的车机端软件加解密方法及装置，涉及完全无人驾驶领域以及辅助驾驶领域，可以先获取待加密数据，待加密数据用于在智能驾驶中的数据传输，通过预设的加密算法对待加密数据进行加密，得到密文数据。而后。可以将该密文数据发送给设定设备，以使该
