Abstract

The embodiment of the invention discloses a security chip communication method and device based on a third-party key management node. According to the technical scheme provided by the embodiment of the invention, the private key information and the corresponding public key information are generated through the third-party key management node, the public key information is configured to the service node according to the second node identifier, the private key information is processed by setting the randomized processing data to obtain the key processing information, and the key processing information is sent to the Internet of Vehicles node; the Internet of Vehicles node processes the key processing information based on set de-randomization processing data to obtain corresponding private key information, and the de-randomization processing data is configured corresponding to randomization processing data in advance; and the Internet of Vehicles node decrypts the encrypted data sent by the service node based on the private key information, wherein the encrypted data is encrypted through the public key information. By adopting the technical means, the cracking difficulty of the communication key information can be improved, the security of communication key information configuration is ensured, and the security of data transmission is further improved.

Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular, to a method and device for communication of a security chip based on a third-party key management node. Background technique [0002] At present, when the business data interaction is performed in the application scenario of the Internet of Vehicles, since the data content may involve the user's personal information, private information, etc., during the business data interaction process, the transmitted data is usually encrypted to avoid data leakage. , causing unnecessary losses to users. The traditional IoV data transmission method is generally that the sender uses the key information provided by the receiver to encrypt the data, and then sets the corresponding decryption key at the data receiver, and uses the decryption key to decrypt the received encrypted data. , so as to realize the secure transmission of data. [0003] However, thi...
