Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0040] 1. Model structural layout of the present invention.

[0041] Such as figure 1 For the overall structure of the present invention, the specific parameters are defined as follows:

[0042] Trusted Authority (TA): It is mainly responsible for the initialization of the system, generating keys for roadside units and users, arbitrating and scoring disputes and revealing the identity of malicious users, assuming that TA is not easy to be captured and is completely credible.

[0043] Roadside Unit (RSU): As a fog node with large storage space, strong computing power and network communication capabilities, the roadside unit node performs shared travel matching according to the information sent by passengers and drivers. The side unit re-encrypts the itinerary ciphertext to generate a re-encrypted ciphertext that the driver can decrypt.

Abstract

A safety sharing travel service scheme based on an alliance block chain comprises a trust mechanism, a roadside unit and users, and the users are composed of passengers and drivers. The passenger encrypts the travel data and the access structure to generate a ciphertext and sends the ciphertext to the roadside unit; the driver sends the travel attribute of the driver to the roadside unit; the roadside unit uses fog calculation to match a proper driver for a passenger, converts a ciphertext into a re-encrypted ciphertext and sends the re-encrypted ciphertext to the driver, the driver decrypts the re-encrypted ciphertext to obtain information and provides a shared travel service for the passenger, and after the shared travel service is finished, the roadside unit stores a ride sharing recordto a block chain for tracing responsibility in case of disputes. According to the method, the requirements of the shared travel service for safety and privacy are met, potential collusion attacks areeffectively resisted, the centralized structure of an existing shared travel service scheme is changed, and communication expenditure and calculation expenditure are reduced.

Description

technical field [0001] The invention belongs to the technical field of information security, and relates to block chain technology in the field of information security, and methods for re-encryption by attribute proxy and data security verification. Background technique [0002] With the development of sharing economy and Internet technology, shared travel has become a new way of travel. In recent years, shared mobility service providers such as Uber and Lyft have provided shared mobility services to millions of users in hundreds of cities. As the largest shared travel service provider in China, Didi Chuxing has 450 million users and provides users with an average of 20 million shared travel services every day. Passengers and drivers publish their own itineraries on the app, such as departure and destination, shared travel service providers match supply and demand based on the information released by passengers and drivers, and then send relevant information about the drive...
