Problems solved by technology

There are many security risks in the mutual communication between a large number of computing units
However, with regard to the security issues of vehicle internal data access and communication between computing modules in the vehicle network, it is currently mainly solved by hardware. This method cannot guarantee the security performance and cannot meet the data security of more and more autonomous vehicles. need

Embodiment

[0142] The following will be divided into two parts to introduce the specific simulation experiment results: the first part is implemented to compare and test the performance of the attribute encryption part of the present invention. This implementation is based on the Charm library (version 0.5b), using Type-III MNT224 curves and asymmetric groups to generate bilinear pairs e:G 1 ⅹG 2 →G T . The other part of this simulation experiment encrypts two types of data, offline and online, to actually test the feasibility of this scheme.

[0143] 1) This implementation adopts the form {Attr 1 and Attr 2 and...and Attr n} strategy, and set the length of the strategy to n. In this experiment, the number of attributes is controlled from 0 to 50, and the number of strategies is also from 0 to 50. Using the control variable method, several schemes of BSW, Waters and FAME were compared. The Waters scheme has better performance, and FAME proves its security under the standard mod...

Abstract

The invention discloses a data access control method suitable for the interior of an automatic driving vehicle. The data access control method sequentially comprises the following steps of initializing corresponding parameters, generating an access strategy and attributes, applying for registration to a TTP by an application program, generating and distributing a secret key by the TTP according toan access tree structure AS, encrypting data, communicating data and updating the secret key. Rapid encryption and decryption can be realized, and the method is suitable for a large attribute set environment; the two secret key updating strategies can achieve fast secret key updating. Meanwhile, an owner can define an access strategy by himself / herself, and the vehicle-mounted application programcan only access data within the authority range of the vehicle-mounted application program, so that the safety and privacy of automatic driving are further improved. In addition, analysis and experiments prove that the calculation and transmission expenses are low, and the scheme is feasible.

Description

technical field [0001] The present invention relates to communication security technology for self-driving vehicles, in particular to a data access control method suitable for self-driving vehicles. Background technique [0002] A self-driving car is a kind of smart car, which can also be called a wheeled mobile robot. It mainly relies on the computer system-based smart driver in the car to realize unmanned driving. Self-driving vehicles are a comprehensive system integrating functions such as environmental perception, planning and decision-making, and multi-level assisted driving. [0003] In order to support the automatic driving function, a large number of various sensors need to be installed on the vehicle. For example, the millimeter-wave radar can accurately detect the distance and speed of the vehicle in front, and has a strong ability to penetrate fog, smoke, and dust; while the camera vision system can Obtain details such as the color and shape of lane lines, traff...
