The embodiment of the invention discloses a data communication method and system based on secondary authentication of adjacent nodes, and the method comprises the steps: transmitting an identification obtaining request to a server if terminal equipment determines that transmission data is secondary authentication data; the server determines current adjacent node information of the terminal equipment and sends the adjacent node information to the terminal equipment; the terminal equipment determines a corresponding auxiliary encryption key according to the adjacent node information, establishes a data transmission link with the adjacent node, encrypts the transmission data through the auxiliary encryption key, and sends the transmission data to the adjacent node; and the adjacent node carries out decryption through the stored auxiliary decryption key, encrypts the decrypted data through the stored encryption key when data transmission is carried out with the server, and sends the encrypted data to the server. According to the scheme, the security of data transmission is improved, and the leakage of privacy data of a user is avoided.
Description
technical field [0001] The embodiments of the present application relate to the technical field of communication security, and in particular, to a data communication method and system based on secondary authentication of adjacent nodes. Background technique [0002] With the popularization of the network and the development of hardware devices, there are more and more applications for realizing networked communication among various devices to realize various complex functions. For example, in vehicle networking communication, vehicle equipment interacts with data from the server. How to ensure secure communication between devices is an important issue that needs to be solved at present. [0003] In the related art, the patent document CN111479244A discloses a V2I vehicle networking identity authentication system and method, including a cloud, at least one roadside terminal and at least one vehicle terminal; the cloud includes a traffic management cloud server, a certificate...
