Embodiment Construction

[0019] In view of the problems existing in the prior art, the present invention proposes an implicit certificate calculation method suitable for the Internet of Vehicles environment.

[0020] In order to make the technical scheme of the present invention more clear, understand, the following reference to the accompanying drawings and cited embodiments, the embodiment of the present invention will be further elaborated in detail.

[0021] Figure 1 Flowchart of an embodiment of the implicit certificate calculation method of the present invention suitable for the Internet of Vehicles environment, e.g., Figure 1As shown, the implicit certificate calculation method suitable for the Internet of Vehicles environment includes steps 11 to 22 as follows:

[0022] Step 11: Generate a pair of key pairs X=xG on the car side;

[0023] Step 12: The car side sends a pair of key pair X to the middle layer;

[0024] Step 13: The middle layer derives X from this key pair i ＝X+f(i)G；

[0025] Step 1...

Abstract

The invention discloses an implicit certificate calculation method suitable for the environment of the Internet of Vehicles. Specifically, the issuing authority can use this method to issue an implicit certificate and reconstruct the key pair at the vehicle end. Moreover, moving some calculations from the issuing agency to the vehicle end greatly reduces the performance requirements of the issuing agency and eases the computing pressure on the issuing agency, thereby meeting the needs of a large number of vehicles in the Internet of Vehicles environment.

Description

Technical field [0001] The present invention relates to the field of cryptography and car networking technology, in particular to the implicit certificate calculation method suitable for the internet of vehicle environment Background [0002] With the vigorous development of the Internet of Vehicles, digital signature and encryption and decryption technology based on public key cryptography are important tools to ensure the security of vehicle-side communication information. [0003] Due to the consideration of vehicle privacy, there is a large number of certification needs in the internet of vehicles environment. [0004] In order to reduce the operational pressure of the issuing authority, a method called an implicit certificate is proposed in the prior art, that is, the public key is not directly reflected in the certificate, and the issuing authority does not need to calculate the public key. [0005] However, the above algorithm causes the computational pressure on the car s...
