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 vehicle networking service request method and device. The method comprises the following steps of: obtaining a service application request, wherein the service application request comprises vehicle information and a service type; performing Attribute-based encryption via ciphertext policy CP-ABE encryption algorithm and transmitting a control strategy encryption service application request to obtain a communication ciphertext including a service application request and an identification of a vehicle networking server; Sending a communication ciphertext including a service application request and a vehicle networking server identification to the vehicle networking server; Receiving a communication cipher text fed back by a vehicle networking server including a service content and a vehicle networking terminal identification; obtaining The service content by decrypting the communication ciphertext containing the service content and the vehicle networking terminal identifier by a preset decryption algorithm and a reception control strategy. The method realizes the access control of the vehicle networking terminal and the vehicle networking server flexibly while ensuring the 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 ...
