Blockchain access authentication method, Internet of Vehicles terminal and operator system

Abstract

The invention discloses a blockchain access authentication method, an Internet of Vehicles terminal, an operator system, a base station and a policy control function entity, and the method comprises the steps: broadcasting an access request for accessing a blockchain in the blockchain if a wireless network or an enterprise private network is searched; receiving a first encrypted message broadcasted by an operator system in the block chain, wherein the first encrypted message is broadcasted in a block chain after an operator system in the block chain encrypts message content by using a sessionkey to generate a first ciphertext and performs attribute encryption on a session to generate a second ciphertext; wherein the first encrypted message comprises a first ciphertext and a second ciphertext; decrypting the first encrypted message to obtain a message content; encrypting the message content by using a service password of the Internet of Vehicles terminal to obtain a second encrypted message; and broadcasting the second encrypted message in a block chain. The Internet of Vehicles terminal can be safely accessed to a wireless network or an enterprise private network.
