Embodiment 1

[0049] This embodiment provides a cloud platform for encrypting location information of the Internet of Vehicles;

[0050] Such as figure 1 As shown, the Internet of Vehicles location information encryption cloud platform is configured as:

[0051] receiving the key acquisition request sent by the terminal;

[0052] Verify the validity of the request and verify the identity of the terminal;

[0053] If the validity of the request and the identity verification of the terminal pass, the pre-generated and stored key is extracted from the database according to the key acquisition request;

[0054] Encrypt the extracted key;

[0055] Send the encrypted key to the terminal.

[0056] Further, the validity of the request is checked, and the identity of the terminal is checked; the specific steps include:

[0057] The cloud platform obtains the AC private key of the terminal;

[0058] Based on the AC private key of the terminal, the cloud platform uses ACA to verify the validity ...

Embodiment 2

[0084] This embodiment provides a terminal for encrypting location information of the Internet of Vehicles;

[0085] The location information encryption terminal of the Internet of Vehicles is configured as:

[0086] Send an application for obtaining a key to the cloud platform;

[0087] The key to receive feedback from the cloud platform;

[0088] Decrypt the feedback key;

[0089] Encrypt the location information of the Internet of Vehicles to be encrypted based on the decrypted key;

[0090] Wherein, the key fed back by the cloud platform is a key generated and stored by the cloud platform; the key is updated regularly.

[0091] It should be understood that the terminal in this application applies for the location information encryption key from the cloud platform to meet the following security requirements: the security and credibility of the application process; the use of AC private key signatures to prove its identity; the security of key calculation and storage ;Ke...

Embodiment 3

[0112] Embodiment 3, the present application provides a system for encrypting location information of the Internet of Vehicles;

[0113] IoV location information encryption cloud system, including: terminal and cloud platform;

[0114] The cloud platform is configured to: receive a key acquisition request sent by a terminal; check the validity of the request and check the identity of the terminal; if both the validity of the request and the identity of the terminal pass, then according to the key Get the request, extract the pre-generated and stored key from the database; encrypt the extracted key; send the encrypted key to the terminal;

[0115] The terminal is configured to: send an application for obtaining a key to the cloud platform; receive a key fed back by the cloud platform; decrypt the fed back key; encrypt the location information of the Internet of Vehicles to be encrypted based on the decrypted key; Wherein, the key fed back by the cloud platform is a key generat...

Abstract

The invention discloses an Internet of Vehicles position information encryption cloud platform, terminal, system and method. The method comprises the following steps: receiving a key acquisition request sent by a terminal; verifying the validity of the request, and verifying the identity of the terminal; if both the validity of the request and the identity verification of the terminal are passed,extracting a pre-generated and pre-stored key from a database according to the key acquisition request; the extracted secret key is encrypted; and the encrypted key is sent to the terminal. Accordingto the invention, the cloud platform can safely generate the symmetric key and store the symmetric key; the cloud platform performs identity authentication on the terminal, and only the legal terminalcan acquire the encryption key from the cloud platform; the symmetric key generated by the cloud platform has a life cycle and can be updated regularly; in the secret key distribution process, the safety of the secret key is ensured in an encryption mode; the key distribution process has the characteristics of high performance and high availability, and the influence of centralized application ofthe terminals on the working performance of the cloud platform is avoided.

Description

technical field [0001] This application relates to the technical field of information encryption, in particular to a cloud platform, terminal, system and method for encrypting location information of the Internet of Vehicles. Background technique [0002] The statements in this section merely mention the background art related to this application, and do not necessarily constitute the prior art. [0003] In the application scenario of the Internet of Vehicles, both the BSM message and the SPDU security message contain the location information (latitude and longitude) of the device. Since the broadcast communication method is used between the devices, this information can be obtained by any other device. If the device location information is transmitted in clear text, criminals can intercept any location information of any device, which poses a major threat to the privacy and security of IoV devices and users. Contents of the invention [0004] In order to solve the defici...
