The present disclosure provides a secure booting method, apparatus, device for an embedded program and a storage medium. The method includes: when a boot program is running, acquiring data of an application program, including signature information, public key information, parameter information, encrypted data, and a digital check code; performing signature check according to the signature information; performing integrity check according to the digital check code if the signature check passes; and performing data decryption according to the public key information and the parameter information if the integrity check passes. The present disclosure may improve information security.

Secure booting method, apparatus, device for embedded program, and storage medium

Provided are a data communication method and system, an electronic device, a chip and a storage medium. The data communication method includes: establishing a wireless communication connection with a first receiving terminal, and notifying the connection information to a second receiving terminal. The connection information includes information of a communication channel for performing wireless communication between the transmitting terminal and the first receiving terminal. The connection information is used to instruct the at least one second receiving terminal to monitor communication data in the communication channel. When the at least one second receiving terminal knows after monitoring the communication data, data required to be transmitted to the first receiving terminal is transmitted to the communication channel. A first time period for the transmitting terminal to transmit data in the communication channel does not overlap a second time period for the at least one second receiving terminal to transmit data in the communication channel.

Data communication method and system, electronic device, chip and storage medium

A method for measuring a power-on reset time includes: detecting a power supply pin voltage of a chip, and recording a time point at which the power supply pin voltage reaches a preset voltage as a first time point; detecting an output signal of a preset pin of the chip, and recording a time point at which the preset pin completes a pulse output for a first time after the chip is powered on, as a second time point, and recording a time point the preset pin completes a pulse output for a second time, as a third time point; wherein widths of the pulse output for the first time and for the second time are the same; and computing the power-on reset time of the chip according to the first time point, the second time point and the third time point.

Method and system for measuring power-on reset time

The present disclosure relates to a key generation method applied to a chip storing an internal key, which includes: acquiring () a first and a second random number; generating () an initial private key of the chip according to the first random number and the internal key, and generating an update private key of the chip according to the second random number and the internal key; generating () an initial public key corresponding to the initial private key according to the initial private key, and generating an update public key corresponding to the update private key according to the update private key; and sending () the initial public key, the update public key, and the second random number to a server that sends the second random number to the chip when receiving a private key update request of the chip, to trigger a private key update of the chip.

Some embodiments of the present disclosure provide a method for detecting a fault of a smart door lock, a smart door lock and a storage medium. The smart door lock includes a plurality of unlocking modules, and the method for detecting a fault of the smart door lock includes: monitoring state information of each of the unlocking modules independently; and sending fault information of an unlocking module in an abnormal state to a terminal device after monitoring the unlocking module in the abnormal state. By adopting the embodiments of the present disclosure, specific fault information of a fault which occurs can be accurately and timely known, and a specific position where the fault occurs may be located, which effectively reduces difficulties in detecting the fault and repairing the smart door lock.

Method for detecting fault of smart door lock, smart door lock and storage medium

Provided are a data communication method and system, an electronic device, a chip and a storage medium. The data communication method includes: establishing a wireless communication connection with a preset first receiving terminal, and notifying the connection information to a second receiving terminal. The connection information includes information of a communication channel for performing wireless communication between the transmitting terminal and the first receiving terminal. The connection information is used to instruct the second receiving terminal to monitor communication data in the communication channel. When the second receiving terminal knows after monitoring the communication data, data required to be transmitted to the first receiving terminal is transmitted to the communication channel. A first time period for the transmitting terminal to transmit data in the communication channel does not overlap a second time period for the second receiving terminal to transmit data in the communication channel.

The present application provides a data management method, apparatus, device, system and storage medium for a smart lock. The smart lock includes: respective databases corresponding to N unlock modes, N is an integer greater than 1, and the method includes: receiving a registration command transmitted by a terminal device; acquiring first unlock information of a current unlock mode according to the registration command; and storing the first unlock information of the current unlock mode into a database corresponding to the current unlock mode. Therefore, unlock efficiency of the smart lock is improved.
