Problems solved by technology

[0004] At present, the public key encryption mechanism has been widely used in the field of data security because it does not require key sharing. The private key can be successfully decrypted, but this scheme can only guarantee the confidentiality of the data, but cannot implement flexible and fine-grained access control to the data

Abstract

The invention discloses a service request method and device for Internet of Vehicles. The method includes: obtaining a service application request, the service application request including vehicle information and service type; encrypting the service application request by encrypting the CP-ABE encryption algorithm based on the attribute of the ciphertext policy and sending the control strategy, and obtaining the service application request and the Internet of Vehicles The communication ciphertext of the server identification; send the communication ciphertext including the service application request and the IoV server identification to the IOV server; receive the communication ciphertext including the service content and the IOV terminal identification fed back by the IoV server; decrypt by preset The algorithm and receiving control strategy decrypt the communication ciphertext containing the service content and the IOV terminal identification to obtain the service content. The invention realizes the flexible access control to the IoV terminal and the IOV server while ensuring data confidentiality.

Description

technical field [0001] The embodiments of the present invention relate to the Internet of Vehicles technology, and in particular to a method and device for requesting a service of the Internet of Vehicles. Background technique [0002] Due to the characteristics of low latency, location awareness, and adaptable mobility of fog computing, fog computing has become more and more widely used, and can be applied to multiple application scenarios such as Internet of Vehicles and intelligent transportation. In the Internet of Vehicles, fog computing can provide a wealth of network services, such as route selection, congestion or accident reminders, driving recorder storage, entertainment information, etc. However, these network services are usually paid subscription services, and only subscribers can obtain the corresponding services. Therefore, service providers need to implement privacy protection and access control for the content of the services provided. [0003] At the same ...
