Validation method of bluetooth base station based on dynamic time

Abstract

The invention belongs to the field of the Internet of Things, and in particular relates to an identity verification method for the Internet of Things through Bluetooth. The purpose is to solve the problem that data may be hijacked during the process of discovering Bluetooth devices by the current central equipment and affect the security of user data. The invention provides a The bluetooth base station legitimacy verification method based on dynamic time comprises the following steps: first, carry out time initialisation setting to central equipment and peripheral equipment, the time of central equipment and the time of peripheral equipment are set as initial time, after setting is completed, central equipment and peripheral equipment The devices are timed separately; then, the peripheral devices broadcast the broadcast data with the current time, and the central device receives the broadcast data with the current time, analyzes and extracts the current time of the peripheral devices, and compares the current time of the peripheral devices with the current time of the central device. Time is compared and verified, and it is judged whether the peripheral device is a legal Bluetooth base station according to the comparison result. The present invention is applicable to the Internet of Things based on Bluetooth.

Description

technical field [0001] The invention belongs to the field of the Internet of Things, in particular to an identity verification method when the Internet of Things is carried out through bluetooth. Background technique [0002] Bluetooth Smart (hereinafter referred to as BLE4.0) is the latest Bluetooth transmission technology standard. BLE4.0 adds the 4.0 Bluetooth specification to the previous Bluetooth transmission standard, aiming at wireless applications and low power consumption, low latency, and small data packet transmission requirements. At present, it has a wide range of applications in the Internet of Things, mobile phones, wearable devices, and automotive electronic devices, and is also developing and improving rapidly. The new generation of BLE4.0 specification, because it is different from the previous Bluetooth specification, removes the requirement of code matching in the process of scanning, discovery and connection, which greatly improves the convenience and ...
