Near field communication data encryption method, terminal device and vehicle

Abstract

The embodiment of the invention provides a near field communication data encryption method, a terminal device and a vehicle. The method runs in a first terminal, and near field communication connection is established between the first terminal and a second terminal. The method comprises the following steps: acquiring second feature information corresponding to the second terminal based on the nearfield communication connection; generating feature keys corresponding to the first terminal and the second terminal according to the first feature information and the second feature information corresponding to the first terminal; and encrypting communication data transmitted through the near field communication connection by using the feature key to generate encrypted data. According to the embodiment of the invention, the feature key corresponding to each terminal device in the near field communication connection can be generated, the communication data is encrypted, and the security of thecommunication data is improved while the convenience is satisfied.

Description

technical field [0001] The invention relates to the technical field of short-distance communication data encryption, in particular to a short-distance communication data encryption method, terminal equipment and a vehicle. Background technique [0002] With the development of communication technology and the diversification of vehicle application scenarios, NFC has attracted increasing attention from equipment manufacturers and is generally favored by users due to its low complexity, convenient use, good applicability and ease of use. [0003] In general, short-distance communication uses plain text or universal encryption when transmitting communication data, which has a relatively large risk of privacy leakage. However, if a complex encryption verification method is used, it needs to rely on a complex server or increase hardware, which will easily cause communication delays and reduce the convenience of use. [0004] At the same time, in many application scenarios, the tr...

[0003] In general, short-distance communication uses plain text or universal encryption when transmitting communication data, which has a relatively large risk of privacy leakage

However, if a complex encryption verification method is used, it needs to rely on complex servers or increase hardware, which will easily cause communication delays and reduce the convenience of use

[0004] At the same time, in many application scenarios, the transmission of communication data is time-consuming. In order to shorten user waiting time and improve user experience, the synchronized communication data is usually cached in the local database of the terminal device. For similar reasons, cached data also has comparisons. Large risk of accidental disclosure or interception
