Safe charging method for bike sharing based on safe position proof

Abstract

The invention discloses a safe charging method for bike sharing based on a safe position proof. The method mainly comprises a position proof generation phase and a position proof verification phase. In the position proof generation phase, when a requester P starts or completes use of a bike, a broadcast request recruit is sent to issuers W in the surrounding, the W respond to a request, P distributes a sub-secret to the W via a safe channel, and the W embed the received sub-secret in a position proof generated by the P, and returns the position proof to the P. In the position proof verification phase, the P makes a declaration of specific position in specific time before settling with a verifier V, and then, the V verifies the authenticity of the position and time in the declaration. On the basis that the driving mileage of the bike can be calculated efficiently and simply, safety attack in a bike charging system is defended, and it is verified that the method is reasonable, correct and effective.

Description

technical field [0001] The invention relates to a charging method for shared bicycles, in particular to a safe charging method for shared bicycles based on secure location proof. Background technique [0002] The rapid development of the mobile Internet has spawned a large number of online to offline (Online To Offline, O2O) sharing economy businesses. Among these shared economic businesses, one type of O2O business has recently developed rapidly, which is shared bicycles. Since the bike-sharing business first appeared on the campus of Peking University in May 2015, many bike-sharing apps including Mobike, Uber, Ofo, Xiaoming, Xiaolan, Qibei, etc. have been born. The birth of these shared bicycle applications has facilitated the daily life of the majority of users, greatly promoted the solution of the last mile problem of people's daily travel, and has been greatly popularized in practical applications. Today, walking in the campuses of colleges and universities in major c...

Considering that many users, especially campus teachers and students, often only ride for less than one kilometer, and the time is mostly 5-10 minutes, this simple method of charging in stages based on the length of the car is undoubtedly different from the actual situation. match

On the other hand, using the user's GPS data to obtain the user's location information will inevitably involve the user's location privacy. As users pay more and more attention to the security of personal information, applications that do not strictly protect location privacy information will inevitably not be obtained. user's favor
