Abstract

The invention discloses a security authentication method and apparatus, and an electronic device. The method comprises the steps of sending a verification request to a verification terminal; receivinga first data packet and obtaining third preset data, fourth preset data, second time data, a control instruction and fifth preset data, wherein the first data packet is determined by the verificationend in response to the verification request; generating a key according to the third preset data, the fourth preset data, the second time data and the first data packet; encrypting the control instruction and fifth preset data according to the key to generate first encrypted data; sending the first encrypted data to a verification end, so that the verification end sends the control instruction and fifth preset data to an execution end, and the execution end executes the control instruction according to the following method: judging whether the fifth preset data is the same as the built-in preset data or not; and if so, executing the control instruction. According to the invention, the interaction process can be reduced, the time delay experience is improved, and the risk of malicious power consumption caused by NFC-Key encryption and decryption behaviors triggered by fake messages of the card reader is reduced.

Description

technical field [0001] The invention relates to the technical field of information security authentication, in particular to a security authentication method, device and electronic equipment. Background technique [0002] NFC (Near Field Communication, Near Field Communication) key is a basic application of the Internet of Vehicles, responsible for key functions such as car door opening and closing, engine starting, etc. The security authentication of the requesting end usually requires the participation of four types of components, namely, the requesting end (marked as NFC-Key), the car-side NFC card reader (marked as NFC-Reader), the car-side NFC controller (marked as NFC-Controlle), Body controller (denoted as Central-Controller). [0003] The NFC-Key and NFC-Reader exchange information, and the NFC-Controlle is responsible for mutual security authentication with the NFC-Key, and finally transmits the sensitive information of the requesting end to the Central-Controller ...
