Abstract

The invention provides an authentication method and an authentication system based on EMQTT server access, a server and a client. The authentication method comprises the steps of: transmitting a bidirectional authentication request to a vehicle infotainment client when an EMQTT server receives an access request transmitted by the vehicle infotainment client; judging whether a server certificate isissued by a PKI certificate management system at the vehicle infotainment client; meanwhile, when a local certificate consistent with the server certificate is inquired in a local certificate list ofthe vehicle infotainment client, transmitting a bidirectional authentication response to the EMQTT server by the vehicle infotainment client; and when the EMQTT server judges that a client certificate is issued by the PKI certificate management system, adopting an SSL / TLS protocol to perform encryption communication by the vehicle infotainment client and the EMQTT server. By adopting the authentication method based on EMQTT server access, the preset PKI certificate management system issues the corresponding server certificate and client certificate to the EMQTT server and the vehicle infotainment client, and the safety communication level between the vehicle infotainment client and the EMQTT server in the Internet of Vehicles is improved through adopting a TLS two-way authentication method.

Description

technical field [0001] The invention belongs to the technical field of Internet of Vehicles, and relates to a server authentication method, in particular to an authentication method, system, server, and client based on EMQTT server access. Background technique [0002] In the Internet of Vehicles environment, the communication between the client of the car and the EMQTT server usually uses TLS one-way authentication or even no encrypted transmission. If malicious attacks are encountered during transmission, the communication information will be read. Communication data, or Tampering with communication data, the security level is low. Contents of the invention [0003] In view of the shortcomings of the prior art described above, the object of the present invention is to provide an authentication method, system, server, and client based on EMQTT server access, which are used to solve the problem between the EMQTT server and the car-machine client in the prior art. The prob...
